We extend the notion of lattice polarization for K3 surfaces to families in a way that gives control over the action of monodromy on the algebraic cycles, and discuss the uses of this new theory in the study of families of K3 surfaces admitting...

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...
