Anomalous subdiffusion in quantum chains

In typical quantum systems with conservation laws, the approach to equilibrium at finite temperature is governed by classical hydrodynamics in which charge and energy diffuse. In this talk, I will discuss some one dimensional quantum systems with anomalous hydrodynamic behavior — that is, systems where diffusion of charge is replaced by subdiffusion or superdiffusion. These systems evade the conventional description by being close to integrable points with enhanced symmetries — nonetheless, recent experiments on similar systems have shown that the behavior can be probed with cold atom experiments.

Pizza and drinks served after the talk.
