This study investigates the effectiveness of spread complexity, a measure of quantum chaos, in characterizing non-Hermitian many-body localization transitions, revealing its ability to distinguish between ergodic and localized phases and detect complex-real eigenvalue transitions.
This study reveals that in a non-Hermitian disordered fermionic chain, boundary conditions significantly influence the system's spectral and localization properties, leading to distinct phases characterized by real or complex eigenspectra and varying degrees of localization.
