Anomalous subdiffusion in quantum chains

November 12, 2021 - 12:00pm
Brayden Ware

Abstract: 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.
