Non-Hermitian skin effects on thermal and many-body localized phases

Localization in one-dimensional interacting systems can be caused by disorder potentials or non-Hermiticity. The former phenomenon is the many-body localization (MBL), and latter non-Hermitian skin effect (NHSE). In this work, we numerically investigate interplay between these two kinds of localization, where energy-resolved MBL arises from a deterministic quasiperiodic potential fermionic chain. We propose set eigenstate properties long-time dynamics that collectively distinguish mechanisms presence By computing proposed diagnostics, show thermal states are vulnerable to NHSE while remain resilient up strong Finally, discuss experimental observables probe difference localizations Our results pave way toward observations on interaction, potential,
