- Description
- It has been the believe that generic quantum many-body systems necessarily approach thermal equilibrium after a long time evolution. However, recently the generality of this assumption of ergodic evolution has been questioned. In this talk, we will discuss how ergodicity, and with that fundamental concepts of statistical mechanics, can break down in a disordered and interacting many-body system. We will analyze the generic phase diagram of such systems, which consist of an ergodic phase at weak disorder and a many-body localized phase at strong disorder. Furthermore, we will discuss Griffiths effects arising from rare regions that become important in the vicinity of the many-body localization transition. We also discuss how the many-body localized phase can be made unstable by a periodic drive and demonstrate how its peculiar properties can be characterized in experiments.
