Abstract
For strong disorder 1D lattice systems can become localized even in the presence of interactions, a phenomenon known as many-body localization. Below the localization transition one can have a plethora of transport types that can be efficiently studied by a boundary-driven Lindblad master equation. Quasiperiodic potential, which without interactions can also lead to localization, on the other hand behaves for small interactions completely differently that a random one. In systems with symmetries, an important example being the Hubbard model, dynamics is even richer. One can analytically show that there can be a coexistence of ballistic, localized as well as diffusive transport.
