*Speaker: *Dr. Michael Knap (Harvard)
*Title:*
Dynamics of disordered many-body systems: from thermal transport to
many-body localization
*Abstract:*
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 localized
(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 unveiled.
