Bath-induced delocalization in interacting disordered spin chains

Over a decade of work has culminated in the consensus that one-dimensional systems, subject to sufficiently large disorder, fail thermalize and possess an extensive set local integrals motion. In this Letter, I will provide numerical evidence for contrary. particular, studies dynamics disordered spin chains which are weakly coupled Markovian bath. Within approach, critical disorder stability quantum avalanches exceeds ${W}^{*}\ensuremath{\gtrsim}20$ random field Heisenberg chain. stark contrast Anderson insulator, avalanche threshold drifts considerably with system size, no saturation studied regime.
