Description
In this talk the transition of a quantum system from an ergodic to a non-ergodic state is discussed from several different perspectives. In the first part of the talk I discuss the formation of quantum glasses in liquids with no quenched disorder. It is shown that weak quantum fluctuations can enhance the loss of ergodicity. In the second part of the talk I discuss many-body localization (MBL), with a focus on dynamics in the thermal phase as well as the question of putative MBL in systems with completely delocalized single particle states. Similarities and differences between standard glass transitions and MBL are discussed.
