Non-equilibrium steady state phases of the interacting Aubry-Andre-Harper model

21 May 2020 Yoo Yongchan Lee Junhyun Swingle Brian

Here we study the phase diagram of the Aubry-Andre-Harper model in the presence of strong interactions as the strength of the quasiperiodic potential is varied. Previous work has established the existence of many-body localized phase at large potential strength; here, we find a rich phase diagram in the delocalized regime characterized by spin transport and unusual correlations...
