Entanglement dynamics of a one-dimensional many-body-localized system coupled to a bath — •Elisabeth Wybo, Michael Knap, and Frank Pollmann — Department of Physics, Technische Universität München, James-Franck-Strasse 1, D-85748 Garching, Germany

In isolated, interacting and strongly disordered quantum systems thermalization may break down, leading to a novel many-body localized phase. However, this special phase will be destroyed if the system is not well isolated from the environment. We investigate how many-body localization is destroyed in systems that are weakly coupled to a Markovian environment. In particular, we study entanglement probes like the negativity in quench setups, and determine their typical scaling. To this aim we use both tensor-network and exact-Krylov techniques.
