Dynamics of disordered many-body systems: from thermal transport to many-body localization

This talk provides an introduction to disordered interacting many-body systems. We analyze the generic phase diagram of such systems, which consists of a thermal phase at weak disorder and a many-body localizated (MBL) phase at strong disorder. Near the phase transition, Griffiths effects become important which result in new rare-region dominated phases. Furthermore, we discuss the response of the different phases to transport probes (e.g. conductivity) as well as non-transport probes (e.g. spin-echo interferometry) and demonstrate how the peculiar properties of the MBL phase can be measured in experiments.
