New team-taught course offered spring 2014: “Differential geometry in classical and quantum mechanics”

1) Introduction and Motivation

We would like to call attention to a new class offered this winter/spring 2014 quarter, being taught jointly by Prof. Daniel Ruberman in Mathematics and Prof. Albion Lawrence in Physics.  This is being listed jointly as Physics 202a (Quantum Field Theory) and Math 221b (Topics in Topology).  It is being team-taught under the auspices of the Brandeis Geometry and Dynamics IGERT program.

This course aims to introduce basic notions of fiber bundles and connections on them, and their application to basic physical examples in classical and quantum mechanics: especially the mechanics of deformable bodies, and Berry’s phase.  The target audience is mathematics and physics students, and mathematically inclined students in physical chemistry, neuroscience, computer science, and economics.  The essential principles here find applications to chemical and neural oscillators and control theory; there have even been suggestions that it is a useful language for describing currency trading.

The mathematics covered here typically appears in advanced courses on quantum and statistical field theory.  However, it has much broader applicability, and the instructors felt that studying more elementary physics examples better highlighted the essential mathematics and lead to a broader perspective that would better prepare students to find new and creative uses for the mathematics.  Furthermore, they allow us to teach a broader audience, as the essential physics background is straightforward and can be explained without the student needing two years of graduate-level physics courses.

This course is essentially a graduate course, but it is certainly appropriate for senior undergraduates with a solid mathematical background (math and physics majors especially).  The modern mathematical language of manifolds and vector bundles will be introduced and used throughout, but with reference to physical and geometric notions.  This will provide physics students with an appropriate vocabulary for further study, while mathematics students can try to grasp the intuition behind the formalism.  Note that the course satisfies one of the IGERT course requirements; however, we strongly encourage non-IGERT students to enroll.

The course is scheduled to take place Mondays and Wednesdays from 2-3:20pm. Continue reading “New team-taught course offered spring 2014: “Differential geometry in classical and quantum mechanics””

Thermalization From Glasses to Black Holes

bangalore2Textbook thermodynamics treats equilibrium states of large systems, in which macroscopic variables (temperature, pressure and so on) remain static, and how small perturbations of such systems relax with time.  There have been a number of exciting recent developments in studying (a) how such equilibrium states are reached in a closed quantum or classical system, and (b) generalizations of thermodynamics to small systems and to systems that are intrinsically out of equilibrium.  This work spans both classical and quantum mechanics, and ties together biological systems, soft matter (such as glasses and granular systems), quantum matter, nuclear physics, quantum information, quantum gravity, and string theory.
This is clearly an area of inquiry in which contact between these different fields will lead to important advances, much as contact between condensed matter and particle physics did for the study of symmetry breaking (the source of multiple Nobel prizes, including this year’s and of the renormalization group.  We (Brandeis Physics  faculty Aparna BaskaranBulbul ChakrabortyMatthew Headrick, and Albion Lawrence) felt that an ideal way to promote this was to put together an intensive series of pedagogical lectures covering recent results in the aforementioned fields.  With the encouragement of the National Science Foundation (due in large part to Brandeis’s IGERT program in Geometry and Dynamics  we took advantage of our deep contacts with the Indian physics community to put together an Advanced Studies Institute (ASI) on thermalization, under the auspices of the new International Center for the Theoretical Sciences (ICTS)  in Bangalore, and co-organized by Chandan Dasgupta  (Indian Institute of Science), Gautam Mandal (TIFR, Mumbai), Sanjib Sabhapandit  (Raman Research Institute and ICTS), and Krishnendu Sengupta  (IACS , Kolkata).
The school was extremely successful, with beautiful lectures on cutting-edge physics from the leading experts in their respective areas.  We recommend these lectures highly to those interested in these subjects.  Links to the lecture notes, and to some related review articles, can be found here:

Quantum Field Theory: An Interdisciplinary Study Group

William Hicks, a grad student in Physics, writes:

    This semester, graduate students from a wide range of departments will be coming together to study quantum field theory (QFT) as part of the interdisciplinary IGERT program. QFT is a subject whose mathematical underpinnings crop up in a wide range of seemingly unrelated fields, and the study group hopes to take advantage of the varied backgrounds of its members. Mathematicians in the group can help provide mathematical rigor, while physicists can help supply the physical intuition for many of the otherwise abstruse corners of the subject.  Students from other disciplines will be able to broaden the discussion by showing how some of the techniques discussed also show up in their fields.

The study group will meet from noon to 1:00 every Wednesday in Goldsmith 226. All are welcome!

IGERT Summer Institute

 The Brandeis IGERT program is hosting its first summer institute starting Wednesday, July 31 and running weekdays through Friday, August 9. This will be a series of lectures by experts inside and outside of Brandeis, together with some student seminars, aimed at graduate students across the sciences, especially (but not exclusively!) those doing theoretical work.

The lectures will run from 9:30-4 every day, with coffee at 9am, and ample time between lectures for questions and conversations.  They will be held in room 055 of the Lemberg Academic Center (note that Domenic’s will be open at that time, so lunch is available nearby).  Those interested in attending should RSVP to Tony Bottaro (bottaro@brandeis.edu) so that we can get a head count for coffee.

The lecturers are:

Parongama Sen (University of Calcutta, Kolkata, India), lecturing on applications of statistical physics to social science problems.

Geometry and Dynamics IGERT Awarded

Brandeis has just been awarded an NSF Integrative Graduate Education and Research Traineeship (IGERT) grant in the mathematical sciences.  The grant, titled Geometry and Dynamics: integrated education in the mathematical sciences, is designed to foster interdisciplinary research and education by and for graduate students across the mathematical and theoretical sciences, including chemistry, economics, mathematics, neuroscience, and physics.  It is structured around a number of themes common to these disciplines: complex dynamical systems, stochastic processes, quantum and statistical field theory; and geometry and topology. We believe that it is the first IGERT awarded for the theoretical (as opposed to laboratory) sciences, and are very excited about what we believe to be a highly novel program which will cement existing interdepartmental relationships and encourage exciting new collaborations in the mathematical sciences, including collaborations between the natural sciences and the International Business School (IBS).

The resolution of a singularity that develops along Ricci flow, understood mathematically by Grigori Perelman.  If the red manifold represents the target space of a string, it is conjectured that the corresponding two-dimensonal field theory describing the string undergoes confinement and develops a mass gap for the degrees of freedom corresponding to the singular regime.

The award, for $2,867,668 spread out over five years, provides funds for graduate student stipends, travel, seminar speakers, and interdisciplinary course development.  It contains activities and research opportunities in partnership with the New England Complex Systems Institute (NECSI) in Cambridge, MA.  It also provides opportunities for research internships at the International Center for the Theoretical Sciences in Bangalore.

The PIs on the grant are: Bulbul Chakraborty (Physics); Albion Lawrence (Physics: lead PI); Blake LeBaron (IBS); Paul Miller (Neuroscience); and Daniel Ruberman (Mathematics).  There are 11 additional affiliated Brandeis faculty across biology, chemistry, mathematics, neuroscience, physics, and psychology.  Contact Albion Lawrence (albion@brandeis.edu) for more information about the program.

Arrays of repulsively coupled Kuramoto oscillators on a triangular lattice organize into domains with opposite helicities in which phases of any three neighboring oscillators either increase or decrease in a given direction. Fig. (a) illustrates these two helicities in which cyan, ma- genta and blue vary in opposite directions. In Fig. (b), white and green regions represent domains of opposite helicities. The red regions indicate the frequency entrained oscillators, which are predominantly seen in the interior of the domains.

Admission to the program is handled through the Ph.D programs in the various disciplines:
