Starting with a few remarks on hurricanes, I will sketch some basic facts about the physics of the Quantum Hall Effect. Assuming that the longitudinal conductance of a two-dimensional electron gas in a uniform magnetic field vanishes, I will explain...

According to first principle quantum mechanics, the evolution of N fermions (particles with antisymmetric wave function) is governed by the many body Schroedinger equation. We are interested, in particular, in the evolution in the mean field regime...

The Goncharov reading group is an informal seminar which will read the paper "Volumes of hyperbolic manifolds and mixed Tate motives" and related materials. We will meet on Wednesdays at 10 am in Simonyi 114.

We consider an harmonic chain perturbed by an energy conserving noise and show that after a space-time rescaling the energy-energy correlation function is given by the solution of a skew-fractional heat equation with exponent 3/4.

I will continue last week's discussion of this model, this time giving sketches of proofs of some of the theorems. No technical background is necessary for this lecture, but for motivation and background it is good to consult the Tue Feb 11 talk...

The Geometric Complexity Theory (GCT) Program is an approach towards P versus NP and other lower bounds using algebraic geometry and representation theory. In this talk, we discuss how essentially all known algebraic circuit lower bounds and...

One of the most studied objects in mathematics is the modular curve, which is the quotient of hyperbolic 2-space by the action of \(\mathrm{SL}_2(\mathbb Z)\). It is naturally the home of modular forms, but it also admits an algebraic structure. The...
