From ergodicity to many-body localization in a one-dimensional interacting non-Hermitian Stark system
From ergodicity to many-body localization in a one-dimensional interacting non-Hermitian Stark system
Recent studies on disorder-induced many-body localization (MBL) in non-Hermitian quantum systems have attracted great interest. However, the non-Hermitian disorder-free MBL still needs to be clarified. We consider a one-dimensional interacting Stark model with nonreciprocal hoppings having time-reversal symmetry, the properties of which are boundary dependent. Under periodic boundary conditions (PBCs), …
