Many-body localization

The phenomenon of many-body localisation received a lot of attention recently, both for its implications in condensed-matter physics of allowing systems to be an insulator even at non-zero temperature as well as in the context of the foundations of quantum statistical mechanics, providing examples of systems showing the absence of thermalisation following out-of-equilibrium dynamics. However, many aspects and features of this phenomenon are far from being well understood, and there is not even agreement in the literature on what the actually defining feature is. We investigate several features and ramifications of this phenomenon: We are concerned with mathematical equivalences between various readings of the phenomenon. We numerically study natural condensed-matter systems and investigate experimentally accessible probes.
