Description
The mechanisms that quantum systems can use to avoid thermalization and retain information in their local degrees of freedom have been a subject of intense research interest for both new fundamental physics and novel applications. These mechanisms, for example, are of great importance for quantum technologies since they can be used to build quantum memory devices. This talk will discuss transport measurements that probe the approach to thermal equilibrium in an open two-dimensional electron system at different densities across the metal-insulator transition. We observe different types of far-from-equilibrium dynamics, including many-body localization (MBL). We establish the phase diagram of the dynamical behavior that shows the crossover between MBL and ergodic regimes as a function of density and bath temperature.
