Quantum thermalization and many-body localization: new insights from theory and experiments with ultra-cold atoms

Recent theoretical work has uncovered surprising richness in the dynamics of strongly interacting quantum systems, defining new classes of dynamics ranging from many-body localization to maximally chaotic behavior. This progress has highlighted fundamental open questions including, for example, the nature of the many body localization phase transition as well as the relation between quantum chaos and hydrodynamic modes in thermalizing systems. In this talk I will focus on how experiments with ultra-cold atoms can help address some of these questions. First, I will review recent progress in confronting the emerging theoretical picture of the MBL phase and phase transition with experimental tests. Then, I will turn to describe a new approach to compute the long time dynamics of thermalizing systems using tensor networks, allowing to compute both hydrodynamic transport properties and characteristics of quantum chaos. I will discuss proposals to test these results in experiments.
