Principal Investigators

...

Professor Isaac Chuang

MIT Professor of Physics and EECS; Principal Investigator, MIT RLE Quanta Group.

Prof. Chuang is a pioneer in the field of quantum information science. His experimental realization of two, three, five, and seven quantum bit quantum computers using nuclear spins in molecules provided the first laboratory demonstrations of many important quantum algorithms, including Shor's quantum factoring algorithm. The error correction, algorithmic cooling, and entanglement manipulation techniques he developed provide new ways to obtain complete quantum control over light and matter, and lay a foundation for possible large-scale quantum information processing systems. Prof. Chuang came to MIT in 2000 from IBM, where he was a research staff member. He received his doctorate in Electrical Engineering from Stanford University, where he was a Hertz Foundation Fellow. Prof. Chuang also holds two bachelors and one masters degrees in Physics and Electrical Engineering from MIT, and was a post-doctoral fellow at Los Alamos National Laboratory and the University of California at Berkeley. He is the author, together with Michael Nielsen, of the textbook Quantum Computation and Quantum Information. [ichaung_[at]_mit.edu]

Department of Physics

The Department of Physics offers undergraduate, graduate, and postgraduate training, with a wide range of options for specialization.

The emphasis of both the undergraduate curriculum and the graduate program is on understanding the fundamental principles that appear to govern the behavior of the physical world, including space and time and matter and energy in all its forms, from the subatomic to the cosmological and from the elementary to the complex.

The Department of Physics strives to be at the forefront of many areas where new physics can be found. Consequently, the department works on problems where extreme conditions may reveal new behavior: from clusters of galaxies or the entire universe to elementary particles or the strings that may be the substructure of these particles; from collisions of nuclei at relativistic velocities that make droplets of matter hotter than anything since the Big Bang to laser-cooled atoms so cold that their wave functions overlap, resulting in a macroscopic collective state, the Bose-Einstein condensate; and from individual atoms to unusual materials, such as high-temperature superconductors and those that are important in biology. Pushing the limits provides the opportunity to observe new general principles and test theories of the structure and behavior of matter and energy.

Bachelor of Science in Physics (Course 8)

Minor in physics, minor in astronomy, undergraduate study.

An undergraduate degree in physics provides an excellent basis not only for graduate study in physics and related fields, but also for professional work in such fields as astrophysics, biophysics, engineering and applied physics, geophysics, management, law, or medicine. The undergraduate curriculum offers students the opportunity to acquire a deep conceptual understanding of fundamental physics. The core departmental requirements begin this process. The student then chooses one of two options to complete the degree: the focused option is designed for students who plan to pursue physics as a career, and is an excellent choice for students who want to experience as deep an engagement as possible with physics; the flexible option also provides a very strong physics framework, and gives students who may want to pursue additional academic interests the flexibility to do so. Both programs prepare students very well for graduate studies in physics, as well as for a variety of academic or research-related careers. Either option provides a considerable amount of time for exploration through electives. Students proceed at the pace and degree of specialization best suited to their individual capacities. Both options lead to the same degree: the Bachelor of Science in Physics.

Physics: Focused Option

This option—which includes three terms of quantum mechanics, 36 units of laboratory experience, and a thesis—is ideal preparation for a career in physics.

In the second year, students take:

Physics III12
Relativity12
Quantum Physics I12
Statistical Physics I12
Classical Mechanics II6

Important skills for experimentation in physics may be acquired by starting an Undergraduate Research Opportunities Program (UROP)  project.

In the third year, students normally take laboratory subjects:


Experimental Physics I
and Experimental Physics II
36

Quantum Physics II
and Quantum Physics III
24

Students should also begin to take the restricted elective subjects, one in mathematics and at least two in physics. The mathematics subjects 18.04 Complex Variables with Applications , 18.075 Methods for Scientists and Engineers , and 18.06 Linear Algebra are particularly popular with physics majors. Topical elective subjects in astrophysics, biological physics, condensed matter, plasma, and nuclear and particle physics allow students to gain an appreciation of the forefronts of modern physics. Students intending to go on to graduate school in physics are encouraged to take the theoretical physics sequence:

Electromagnetism II12
Statistical Physics II12
Classical Mechanics III12

An important component of this option is the thesis, which is a physics research project carried out under the guidance of a faculty member. Many thesis projects grow naturally out of UROP projects. Students should have some idea of a thesis topic by the middle of the junior year. A thesis proposal must be submitted before registering for thesis units and no later than Add Date of the fall term of the senior year.

A relatively large amount of elective time usually becomes available during the fourth year and can be used either to deepen one's background in physics or to explore other disciplines.

Physics: Flexible Option

This option is designed for students who wish to develop a strong background in the fundamentals of physics and then build on this foundation as they prepare for career paths that may or may not involve a graduate degree in physics. Many students find an understanding of the basic concepts of physics and an appreciation of the physicist's approach to problem solving an excellent preparation for the growing spectrum of nontraditional, technology-related career opportunities, as well as for careers in business, law, medicine, or engineering. Additionally, the flexible option makes it more possible for students with diverse intellectual interests to pursue a second major in another department.

The option begins with the core subjects:

Physics I12
Physics II12
Physics III12
Quantum Physics I12
Statistical Physics I12
Physics of Energy12
or  Classical Mechanics II

Students round out their foundation material with either an additional quantum mechanics subject ( 8.05 Quantum Physics II ) or a subject in relativity ( 8.20 Introduction to Special Relativity or 8.033 Relativity ). There is an experimental requirement of 8.13 Experimental Physics I or, with the approval of the department, a laboratory subject of similar intensity in another department, an experimental research project or senior thesis, or an experimentally oriented summer externship. An exploration requirement consists of one elective subject in physics. Students can satisfy the departmental portion of the Communication Requirement by taking two of the following subjects:

Quantum Physics III12
Experimental Physics I18
Experimental Physics II18
Einstein, Oppenheimer, Feynman: Physics in the 20th Century12
Forty-three Orders of Magnitude12
Observational Techniques of Optical Astronomy15

The department and the Subcommittee on the Communication Requirement may accept substitution of one of the department's two required CI-M subjects with a CI-M subject in another department if it forms a natural part of the student's physics program.

Students following this option must also complete a focus requirement—three subjects forming one intellectually coherent unit in some area (not necessarily physics), subject to the approval of the department and separate from those used by the student to satisfy the HASS requirement. Areas of focus chosen by students have included astronomy, biology, computational physics, theoretical physics, nanotechnology, history of science, science and technology policy, philosophy, and science teaching. Some students may choose to satisfy their experimental and exploration requirements in the same area as their focus; others may opt for greater breadth by choosing other fields to fulfill these requirements.

Although students may choose this option at any time in their undergraduate career, many decide on the flexible major during their sophomore year in order to have enough time to craft a program that best suits their individual needs. Specific subject choices for the experimental and focus requirements require the written approval of the Flexible Program coordinator, Dr. Sean P. Robinson.

The Minor in Physics provides a solid foundation for the pursuit of a broad range of professional activities in science and engineering. The requirements for a Minor in Physics are as follows: 

Differential Equations 12
Select five Course 8 subjects beyond the General Institute Requirements57-60
Total Units69-72
Differential Equations is also acceptable.

Students should submit a completed Minor Application Form to Physics Academic Programs, Room 4-315. The Physics Department's minor coordinator is Shannon Larkin. See Undergraduate Education for more information on minor programs .

The Minor in Astronomy , offered jointly with the Department of Earth, Atmospheric, and Planetary Sciences, covers the observational and theoretical foundations of astronomy. For a description of the minor, see Interdisciplinary Programs.

Additional information concerning degree programs and research activities may be obtained by contacting the department office , Room 4-315, 617-253-4841.

Master of Science in Physics

Doctor of philosophy, graduate study.

The Physics Department offers programs leading to the degrees of Master of Science in Physics and Doctor of Philosophy.

Admission Requirements for Graduate Study

Students intending to pursue graduate work in physics should have as a background the equivalent of the requirements for the Bachelor of Science in Physics from MIT. However, students may make up some deficiencies over the course of their graduate work.

The normal degree program in the department leads to a PhD in Physics. Admission to a master's degree program in Physics is available only in special cases (e.g., US military officers). The requirements for the Master of Science in Physics are the same as the General Degree Requirements listed under Graduate Education. A master's thesis must represent a piece of independent research work in any of the fields described below, and must be carried out under the supervision of a department faculty member. No fixed time is set for the completion of a master's program; two years of work is a rough guideline. There is no language requirement for this degree.

Candidates for the Doctor of Philosophy or Doctor of Science are expected to enroll in those basic graduate subjects that prepare them for the general examination, which must be passed no later than in the seventh term after initial enrollment. Students are required to take two subjects in the candidate's doctoral research area (specialty requirement) and two subjects outside the candidate's field of specialization (breadth requirement). In addition, all students in the first year of the PhD program must enroll in two semesters of 8.398, a seminar specifically for first-year students. Half of the breadth requirement may be satisfied through a departmentally approved industrial internship. The doctoral thesis must represent a substantial piece of original research, carried out under the supervision of a department faculty member.

The Physics Department faculty members offer subjects of instruction and are engaged in research in a variety of fields in experimental and theoretical physics. This broad spectrum of activities is organized in the divisional structure of the department, presented below. Graduate students are encouraged to contact faculty members in the division of their choice to inquire about opportunities for research, and to pass through an apprenticeship (by signing up for Pre-Thesis Research) as a first step toward an engagement in independent research for a doctoral thesis.

Research Divisions

Faculty and students in the Department of Physics are generally affiliated with one of several research divisions:

  • Astrophysics
  • Experimental Nuclear and Particle Physics
  • Atomic Physics, Biophysics, Condensed Matter Physics, and Plasma Physics
  • Theoretical Nuclear and Particle Physics

Much of the research in the department is carried out as part of the work of various interdisciplinary laboratories and centers, including the Center for Materials Science and Engineering, Francis Bitter Magnet Laboratory, Haystack Observatory, Laboratory for Nuclear Science, Microsystems Technology Laboratories, MIT Kavli Institute for Astrophysics and Space Research, Plasma Science and Fusion Center, Research Laboratory of Electronics, and Spectroscopy Laboratory. Additional information about interdisciplinary laboratories and centers can be found under Research and Study . These facilities provide close relationships among the research activities of a number of MIT departments and give students opportunities for contact with research carried out in disciplines other than physics.

Additional information on degree programs, research activities, admissions, financial aid, teaching and research assistantships may be obtained by contacting the department office , Room 4-315, 617-253-4851.

The MIT Quantum Science and Engineering collective is led by a steering committee and a broader advisory council .

Professor of Physics
Professor of Electrical Engineering

Ike Chuang is a pioneer in the field of quantum information science. His experimental realization of two, three, five, and seven quantum bit quantum computers using nuclear spins in molecules provided the first laboratory demonstrations of many important quantum algorithms, including Shor's quantum factoring algorithm. The error correction, algorithmic cooling, and entanglement manipulation techniques he developed provide new ways to obtain complete quantum control over light and matter, and lay a foundation for possible large-scale quantum information processing systems.

Chuang came to MIT in 2000 from IBM, where he was a research staff member. He received his doctorate in electrical engineering from Stanford University, where he was a Hertz Foundation Fellow. Chuang holds two bachelors and one master's degrees in physics and electrical engineering from MIT, and was a postdoc fellow at Los Alamos National Laboratory and the University of California at Berkeley. He is the author, together with Michael Nielsen, of the textbook Quantum Computation and Quantum Information .

John D. MacArthur Professor of Physics
Director, MIT-Harvard Center for Ultracold Atoms
Associate Director, Research Laboratory of Electronics

Wolfgang Ketterle's research is in atomic physics and laser spectroscopy, particularly in the area of laser cooling and trapping of neutral atoms with the goal of exploring new aspects of ultracold atomic matter. Ketterle conducts experimental research in atomic physics and laser spectroscopy and focuses currently on Bose-Einstein condensation in dilute atomic gases. He was among the first scientists to observe this phenomenon in 1995, and realized the first atom laser in 1997. 

Ketterle joined MIT’s Department of Physics in 1993 where he is the John D. MacArthur Professor of Physics. Ketterle holds a master’s degree from the Technical University of Munich and a PhD in physics from the University of Munich. He conducted postdoctoral research at the Max-Planck Institute for Quantum Optics, the University of Heidelberg, and at MIT. In 2001, the Nobel Prize in Physics was awarded jointly to Eric A. Cornell, Wolfgang Ketterle, and Carl E. Wieman "for the achievement of Bose-Einstein condensation in dilute gases of alkali atoms, and for early fundamental studies of the properties of the condensates."

Physics Professor of the Practice

Morss Professor of Applied Mathematics

Peter Shor consolidated the field of quantum computation by designing the quantum algorithm for factoring large numbers. He proved that a quantum computer could solve a hard computational problem exponentially faster than any classical computer. He also introduced quantum error correcting codes and fault tolerant quantum computation. The theory of error correcting codes is now a well-established branch of this science, substantiating the possibility for error-free quantum computation.

Shor joined the Department of Mathematics in 2003 from his research staff position at AT&T. He received his PhD in applied mathematics from MIT and completed postdoctoral fellowship at the Mathematical Science Research Institute. He is a member of the National Academy of Science and is a fellow of the American Academy of Arts and Sciences.

Doctoral Degrees

A doctoral degree requires the satisfactory completion of an approved program of advanced study and original research of high quality..

Please note that the Doctor of Philosophy (PhD) and Doctor of Science (ScD) degrees are awarded interchangeably by all departments in the School of Engineering and the School of Science, except in the fields of biology, cognitive science, neuroscience, medical engineering, and medical physics. This means that, excepting the departments outlined above, the coursework and expectations to earn a Doctor of Philosophy and for a Doctor of Science degree from these schools are generally the same. Doctoral students may choose which degree they wish to complete.

Applicants interested in graduate education should apply to the department or graduate program conducting research in the area of interest. Some departments require a doctoral candidate to take a “minor” program outside of the student’s principal field of study; if you wish to apply to one of these departments, please consider additional fields you may like to pursue.

Below is a list of programs and departments that offer doctoral-level degrees.

Core course tips

Pictured: Killian Court in springtime

If you’re a new student, you may be wondering a lot about the written diagnostic exams for the core courses. (These exams are sometimes referred to as the written exam, Part 2, the written qualifier, quals, etc. by various people. They’re all the same thing.) You have come to the right place!

At MIT, all graduate students are required to take four core courses, two or three courses in their area of research, and two breadth courses. The four core courses are:

Classical mechanics

Electricity and magnetism

Quantum mechanics

Statistical mechanics

There are two ways to meet the core requirement: either by passing the relevant course with a grade of B+ or by testing out via a corresponding exam. It’s not a qualifying exam. It’s just a way to see where you’re at and potentially test out of courses.

PGSC strongly urges all first-year students to make an attempt at all four written exams in their first August, no matter how you think you’re going to do. There are three reasons for this: (1) it’ll serve as a good diagnostic to help you see where you’re at, (2) no matter how you think you’ll do, you might get lucky and get a question you know how to do, and (3) it’s good practice for the next time around, when you’ll have to take the exam. There is absolutely zero penalty for taking the exam, no matter how you do, and the exams are anonymous so the graders won’t know who you are.

Students come to our program from a wide variety of academic backgrounds and life experiences, and every year there are diagnostic exam results ranging across the entire spectrum. Yes, it is not uncommon at all that a student won’t pass any on their first try — and there are even some who don’t pass until the last try! – and there is nothing wrong with that!  The exam helps serve as a diagnostic to help you and your advisor figure out what material you need to learn or review, and to help you devise a coursework plan for your first few semesters at MIT. Written Exam scores are not indicative of academic potential or future performance; students beginning from all starting points in their first August go on to complete the Ph.D. program, do groundbreaking research, and have successful career.

Let’s say you want to brush up on basic physics, though, or maybe even prepare for one or more of these exams. Perhaps you’re super rusty and haven’t taken any physics courses in a long, long time; whether you’ve been out in the workforce, taking a gap year, or doing a research master’s on string theory, classical mechanics now looks like a foreign language. Or maybe you made some coursework choices your first year at MIT that you might not have made with 20/20 hindsight, and your deadlines for finishing these requirements are coming up. Perchance you don’t have (m)any friends or family members who have gone to grad school in the sciences before, and you’re realizing that you have no idea what you’ve signed yourself up for. Don’t worry. You’re not alone.

But where do you begin?

There are a few different approaches you can take to learning the material, depending on what suits your learning style best:

  • Watching videos and working through a formal course
  • Reading notes or textbooks,
  • Reviewing and memorizing relevant formulas
  • Working through old problems alongside their solutions,

or some combination of the above. Here are some tips!

Online Coursework

One of the great things about MIT is they put a lot online through OpenCourseWare . You can find class notes, videos, homework, exams, and sometimes solutions to all of the above without every having to show up to a class. Here are all the relevant core courses and their numbers, from intro undergrad all the way up through the hardest grad classes. (One small note about the grad courses: usually they cover some topics beyond what could be tested on the written exam.)

Sometimes you can also find archives of old classes on MIT’s old class site Stellar , or you can ask senior graduate students in your division or UROP friends to send you lecture notes or old problem sets from classes they took. Do not underestimate your professors’ willingness to find you course materials as well.

Don’t be embarrassed about going all the way back to the beginning, if that’s what you need. It’s perfectly fine.

  • 8.01 – introductory mechanics
  • 8.223 – intermediate mechanics
  • 8.09/8.309 – classical mechanics III (graduate)
  • 8.02 – introductory E&M
  • 8.07 – intermediate E&M
  • 8.311 – graduate E&M
  • 8.04 – quantum physics I
  • 8.05 – quantum physics II
  • 8.321 – graduate quantum mechanics
  • MIT also offers additional quantum courses like 8.06 and 8.322 , but the ones we’ve listed above are the traditional sequence to prepare for the exam
  • 8.044 – statistical mechanics I
  • 8.08 – statistical mechanics II
  • 8.333 – graduate statistical mechanics
  • MIT also offers another statistical mechanics course, 8.334 , that is the sequel to the core course

Textbook recommendations

If you’re coming straight from college, generally whichever textbook you used in your core classes there probably will suffice for preparing for MIT’s exams and coursework. If you don’t remember what you used, the Physics Department offers a set of textbook recommendations .

Back to square 1? 

If it’s been a long while since you’ve taken any undergrad-level physics courses — whether you’ve taken a gap between undergrad and grad school, or you’ve been focused on a master’s project and settled into a rhythm of just looking up the basics when you need them —  and you find yourself needing to go all the way back to the beginning on a lot of topics, we find that a good place to start is the  Feynman Lectures on Physics . You can usually find a cheap copy on the internet, or if you’re already enrolled at MIT, there are plenty of copies in the library. The Feynman Lectures are notoriously difficult to learn from as a new physics student, but if you’re going back to review, they might very well be perfect for you. They’re entertaining, and unlike a standard textbook, you won’t have to spend too much time trying to dig up the pertinent facts from a mess of examples and instruction on how to do math; the lectures are pretty streamlined. Landau and Lifshitz also have a very thin and very good book on classical mechanics.

Many thanks to Bob Jaffe for making these recommendations initially.

Formula sheets

Maybe you’re at the point now where you have the concepts down pat, or you only have a couple days to go before the exam, and you want to brush up on all the relevant equations and make yourself a formula sheet. Here are some ideas.

These sheets don’t necessarily have everything you need, but they are at least a good place to start!

  • CM:  AP Physics formula sheet ; equations from Iain Stewart’s review notes  about Lagrangian and Hamiltonian mechanics
  • E&M: AP Physics  formula sheet , Alan Guth’s long  formula sheet for 8.07
  • QM: Barton Zwiebach’s formula sheet for 8.05
  • SM: formula sheets embedded in the final exams for 8.044. It’s not enough, but it will get you started.

Old problems

As you’ll hear from many an MIT professor, there is absolutely no difference between a student who “knows physics” and a student who learns how to do the few dozen or so problem types that can come up on an exam of a certain subject area. So one way to tackle an exam is just to make sure that (1) you’ve seen a good smattering of problem types, (2) you have a general idea about how to tackle each one, and (3) you’ve worked through as many as you can (either alongside the solutions or not, depending on how much you’ve had time to review).

You’ll notice as you start working through problems that they get reused a lot , both within our own department and across different institutions! So where do you find these problems?

Old MIT qualifying exams

  • The department posts a number of recent exams and solutions online
  • The PhysREFS have even more exam scans on their webpage
  • There are more old problems (and sometimes solutions) in the Physics Reading Room from the 80’s and 90’s
  • Senior graduate students often have scans of old qualifying exams (and course exams!) as well (or remember what questions they got on their exams) — just ask! If nobody you know knows things, hit PGSC or PhysREFS up and we can try to connect you with resources.
  • There are even books online with sets of old problems from MIT (and other institutions) — particularly the Problems and Solutions in Physics Series of books. These were originally published in the 90’s, so they have lots of older problems as well

Qualifying exams from elsewhere

You can find lots of old problems online from other places. Many of these same problem types may appear on MIT exams. (Though be aware that difficulty level and material covered may vary between institutions.)

  • Princeton preliminary exams  (solutions can be found here )
  • Yale quals and solutions
  • Columbia  quals and solutions
  • Problem bank from Texas A&M’s physics department  (conveniently grouped by topic all in one document)

The plasma research effort at MIT is concerned with a wide variety of problems, ranging from astrophysical plasmas to laboratory and fusion-grade plasmas, as well as with using plasmas for environmental remediation. This work combines theory and experiment and involves faculty members from physics and other departments. The program has the goals of understanding the physics of plasmas and charged-particle beams and of designing plasma containment devices, with the ultimate aim of achieving the conditions in which a plasma can ignite by fusion reactions. Research is carried out not only on-site, but also at other major national and international laboratories.

Most of the volume of the universe is in the electrodynamic plasma state. Moreover, the dynamics of the universe on a grand scale is described as a gravitational plasma. The theory of galaxies as gravitational plasmas is well-developed and its results, for example, spiral arm structures, are relatively well-correlated with the experimental observations. While many aspects of laboratory plasmas are understood and correlate with experiments in relatively simple magnetic geometries, the physics of high-temperature plasmas on a microscopic scale continues to be an area of intensive investigation.

The dynamics of laboratory plasmas, charged-particle beams, and space and astrophysical plasmas are often strongly influenced by the excitation of collective modes with similar characteristics and common theoretical descriptions. The interaction of collective modes, both with each other and with charged particles, results in a variety of highly nonlinear phenomena of great importance for fusion, astrophysical and nonneutral plasmas, as well as for accelerators and coherent radiation sources.

Fourteen MIT School of Science professors receive tenure for 2022 and 2023

In 2022, nine MIT faculty were granted tenure in the School of Science:

Gloria Choi examines the interaction of the immune system with the brain and the effects of that interaction on neurodevelopment, behavior, and mood. She also studies how social behaviors are regulated according to sensory stimuli, context, internal state, and physiological status, and how these factors modulate neural circuit function via a combinatorial code of classic neuromodulators and immune-derived cytokines. Choi joined the Department of Brain and Cognitive Sciences after a postdoc at Columbia University. She received her bachelor’s degree from the University of California at Berkeley, and her PhD from Caltech. Choi is also an investigator in The Picower Institute for Learning and Memory.

Nikta Fakhri develops experimental tools and conceptual frameworks to uncover laws governing fluctuations, order, and self-organization in active systems. Such frameworks provide powerful insight into dynamics of nonequilibrium living systems across scales, from the emergence of thermodynamic arrow of time to spatiotemporal organization of signaling protein patterns and discovery of odd elasticity. Fakhri joined the Department of Physics in 2015 following a postdoc at University of Göttingen. She completed her undergraduate degree at Sharif University of Technology and her PhD at Rice University.

Geobiologist Greg Fournier uses a combination of molecular phylogeny insights and geologic records to study major events in planetary history, with the hope of furthering our understanding of the co-evolution of life and environment. Recently, his team developed a new technique to analyze multiple gene evolutionary histories and estimated that photosynthesis evolved between 3.4 and 2.9 billion years ago. Fournier joined the Department of Earth, Atmospheric and Planetary Sciences in 2014 after working as a postdoc at the University of Connecticut and as a NASA Postdoctoral Program Fellow in MIT’s Department of Civil and Environmental Engineering. He earned his BA from Dartmouth College in 2001 and his PhD in genetics and genomics from the University of Connecticut in 2009.

Daniel Harlow researches black holes and cosmology, viewed through the lens of quantum gravity and quantum field theory. His work generates new insights into quantum information, quantum field theory, and gravity. Harlow joined the Department of Physics in 2017 following postdocs at Princeton University and Harvard University. He obtained a BA in physics and mathematics from Columbia University in 2006 and a PhD in physics from Stanford University in 2012. He is also a researcher in the Laboratory for Nuclear Science’s Center for Theoretical Physics.

A biophysicist, Gene-Wei Li studies how bacteria optimize the levels of proteins they produce at both mechanistic and systems levels. His lab focuses on design principles of transcription, translation, and RNA maturation. Li joined the Department of Biology in 2015 after completing a postdoc at the University of California at San Francisco. He earned an BS in physics from National Tsinghua University in 2004 and a PhD in physics from Harvard University in 2010.

Michael McDonald focuses on the evolution of galaxies and clusters of galaxies, and the role that environment plays in dictating this evolution. This research involves the discovery and study of the most distant assemblies of galaxies alongside analyses of the complex interplay between gas, galaxies, and black holes in the closest, most massive systems. McDonald joined the Department of Physics and the Kavli Institute for Astrophysics and Space Research in 2015 after three years as a Hubble Fellow, also at MIT. He obtained his BS and MS degrees in physics at Queen’s University, and his PhD in astronomy at the University of Maryland in College Park.

Gabriela Schlau-Cohen combines tools from chemistry, optics, biology, and microscopy to develop new approaches to probe dynamics. Her group focuses on dynamics in membrane proteins, particularly photosynthetic light-harvesting systems that are of interest for sustainable energy applications. Following a postdoc at Stanford University, Schlau-Cohen joined the Department of Chemistry faculty in 2015. She earned a bachelor’s degree in chemical physics from Brown University in 2003 followed by a PhD in chemistry at the University of California at Berkeley.

Phiala Shanahan’s research interests are focused around theoretical nuclear and particle physics. In particular, she works to understand the structure and interactions of hadrons and nuclei from the fundamental degrees of freedom encoded in the Standard Model of particle physics. After a postdoc at MIT and a joint position as an assistant professor at the College of William and Mary and senior staff scientist at the Thomas Jefferson National Accelerator Facility, Shanahan returned to the Department of Physics as faculty in 2018. She obtained her BS from the University of Adelaide in 2012 and her PhD, also from the University of Adelaide, in 2015.

Omer Yilmaz explores the impact of dietary interventions on stem cells, the immune system, and cancer within the intestine. By better understanding how intestinal stem cells adapt to diverse diets, his group hopes to identify and develop new strategies that prevent and reduce the growth of cancers involving the intestinal tract. Yilmaz joined the Department of Biology in 2014 and is now also a member of Koch Institute for Integrative Cancer Research.

In 2023, five MIT faculty were granted tenure in the School of Science:

Physicist Riccardo Comin explores the novel phases of matter that can be found in electronic solids with strong interactions, also known as quantum materials. His group employs a combination of synthesis, scattering, and spectroscopy to obtain a comprehensive picture of these emergent phenomena, including superconductivity, (anti)ferromagnetism, spin-density-waves, charge order, ferroelectricity, and orbital order. Comin joined the Department of Physics in 2016 after postdoctoral work at the University of Toronto. He completed his undergraduate studies at the Universita’ degli Studi di Trieste in Italy, where he also obtained a MS in physics in 2009. Later, he pursued doctoral studies at the University of British Columbia, Canada, earning a PhD in 2013.

Netta Engelhardt researches the dynamics of black holes in quantum gravity and uses holography to study the interplay between gravity and quantum information. Her primary focus is on the black hole information paradox, that black holes seem to be destroying information that, according to quantum physics, cannot be destroyed. Engelhardt was a postdoc at Princeton University and a member of the Princeton Gravity Initiative prior to joining the Department of Physics in 2019. She received her BS in physics and mathematics from Brandeis University and her PhD in physics from the University of California at Santa Barbara. Engelhardt is a researcher in the Laboratory for Nuclear Science’s Center for Theoretical Physics and the Black Hole Initiative at Harvard University.

Mark Harnett studies how the biophysical features of individual neurons endow neural circuits with the ability to process information and perform the complex computations that underlie behavior. As part of this work, his lab was the first to describe the physiological properties of human dendrites. He joined the Department of Brain and Cognitive Sciences and the McGovern Institute for Brain Research in 2015. Prior, he was a postdoc at the Howard Hughes Medical Institute’s Janelia Research Campus. He received his BA in biology from Reed College in Portland, Oregon and his PhD in neuroscience from the University of Texas at Austin.

Or Hen investigates quantum chromodynamic effects in the nuclear medium and the interplay between partonic and nucleonic degrees of freedom in nuclei. Specifically, Hen utilizes high-energy scattering of electron, neutrino, photon, proton and ion off atomic nuclei to study short-range correlations: temporal fluctuations of high-density, high-momentum, nucleon clusters in nuclei with important implications for nuclear, particle, atomic, and astrophysics. Hen was an MIT Pappalardo Fellow in the Department of Physics from 2015 to 2017 before joining the faculty in 2017. He received his undergraduate degree in physics and computer engineering from the Hebrew University and earned his PhD in experimental physics at Tel Aviv University.

Sebastian Lourido is interested in learning about the vulnerabilities of parasites in order to develop treatments for infectious diseases and expand our understanding of eukaryotic diversity. His lab studies many important human pathogens, including Toxoplasma gondii , to model features conserved throughout the phylum. Lourido was a Whitehead Fellow at the Whitehead Institute for Biomedical Research until 2017, when he joined the Department of Biology and became a Whitehead Member. He earned his BS from Tulane University in 2004 and his PhD from Washington University in St. Louis in 2012.

Typically, electrons are free agents that can move through most metals in any direction. When they encounter an obstacle, the charged particles experience friction and scatter randomly like colliding billiard balls.

But in certain exotic materials, electrons can appear to flow with single-minded purpose. In these materials, electrons may become locked to the material’s edge and flow in one direction, like ants marching single-file along a blanket’s boundary. In this rare “edge state,” electrons can flow without friction, gliding effortlessly around obstacles as they stick to their perimeter-focused flow. Unlike in a superconductor, where all electrons in a material flow without resistance, the current carried by edge modes occurs only at a material’s boundary.

Now MIT physicists have directly observed edge states in a cloud of ultracold atoms. For the first time, the team has captured images of atoms flowing along a boundary without resistance, even as obstacles are placed in their path. The results, which appear today in Nature Physics , could help physicists manipulate electrons to flow without friction in materials that could enable super-efficient, lossless transmission of energy and data.

“You could imagine making little pieces of a suitable material and putting it inside future devices, so electrons could shuttle along the edges and between different parts of your circuit without any loss,” says study co-author Richard Fletcher, assistant professor of physics at MIT. “I would stress though that, for us, the beauty is seeing with your own eyes physics which is absolutely incredible but usually hidden away in materials and unable to be viewed directly.”

The study’s co-authors at MIT include graduate students Ruixiao Yao and Sungjae Chi, former graduate students Biswaroop Mukherjee PhD ’20 and Airlia Shaffer PhD ’23, along with Martin Zwierlein, the Thomas A. Frank Professor of Physics. The co-authors are all members of MIT’s Research Laboratory of Electronics and the MIT-Harvard Center for Ultracold Atoms.

Forever on the edge

Physicists first invoked the idea of edge states to explain a curious phenomenon, known today as the Quantum Hall effect, which scientists first observed in 1980, in experiments with layered materials, where electrons were confined to two dimensions. These experiments were performed in ultracold conditions, and under a magnetic field. When scientists tried to send a current through these materials, they observed that electrons did not flow straight through the material, but instead accumulated on one side, in precise quantum portions.

To try and explain this strange phenomenon, physicists came up with the idea that these Hall currents are carried by edge states. They proposed that, under a magnetic field, electrons in an applied current could be deflected to the edges of a material, where they would flow and accumulate in a way that might explain the initial observations. “The way charge flows under a magnetic field suggests there must be edge modes,” Fletcher says. “But to actually see them is quite a special thing because these states occur over femtoseconds, and across fractions of a nanometer, which is incredibly difficult to capture.”

Rather than try and catch electrons in an edge state, Fletcher and his colleagues realized they might be able to recreate the same physics in a larger and more observable system. The team has been studying the behavior of ultracold atoms in a carefully designed setup that mimics the physics of electrons under a magnetic field.

“In our setup, the same physics occurs in atoms, but over milliseconds and microns,” Zwierlein explains. “That means that we can take images and watch the atoms crawl essentially forever along the edge of the system.”

A spinning world

In their new study, the team worked with a cloud of about 1 million sodium atoms, which they corralled in a laser-controlled trap, and cooled to nanokelvin temperatures. They then manipulated the trap to spin the atoms around, much like riders on an amusement park Gravitron.

“The trap is trying to pull the atoms inward, but there’s centrifugal force that tries to pull them outward,” Fletcher explains. “The two forces balance each other, so if you’re an atom, you think you’re living in a flat space, even though your world is spinning. There’s also a third force, the Coriolis effect, such that if they try to move in a line, they get deflected. So these massive atoms now behave as if they were electrons living in a magnetic field.”

Into this manufactured reality, the researchers then introduced an “edge,” in the form of a ring of laser light, which formed a circular wall around the spinning atoms. As the team took images of the system, they observed that when the atoms encountered the ring of light, they flowed along its edge, in just one direction.

“You can imagine these are like marbles that you’ve spun up really fast in a bowl, and they just keep going around and around the rim of the bowl,” Zwierlein offers. “There is no friction. There is no slowing down, and no atoms leaking or scattering into the rest of the system. There is just beautiful, coherent flow.”

“These atoms are flowing, free of friction, for hundreds of microns,” Fletcher adds. “To flow that long, without any scattering, is a type of physics you don’t normally see in ultracold atom systems.”

This effortless flow held up even when the researchers placed an obstacle in the atoms’ path, like a speed bump, in the form of a point of light, which they shone along the edge of the original laser ring. Even as they came upon this new obstacle, the atoms didn’t slow their flow or scatter away, but instead glided right past without feeling friction as they normally would.

“We intentionally send in this big, repulsive green blob, and the atoms should bounce off it,” Fletcher says. “But instead what you see is that they magically find their way around it, go back to the wall, and continue on their merry way.”

The team’s observations in atoms document the same behavior that has been predicted to occur in electrons. Their results show that the setup of atoms is a reliable stand-in for studying how electrons would behave in edge states.

“It’s a very clean realization of a very beautiful piece of physics, and we can directly demonstrate the importance and reality of this edge,” Fletcher says. “A natural direction is to now introduce more obstacles and interactions into the system, where things become more unclear as to what to expect.”
