Stable real-energy spectral dynamics with topological transitions and non-Hermitian many-body localization
In this paper, the interplay between non-Hermiticity, quasidisorder, and repulsive interaction is studied for hard-core bosons confined in a one-dimensional optical lattice, where non-Hermiticity is induced by the nonreciprocal hoppings and the on-site gain and loss breaking the time-reversal symmetry. Although the energy spectra of the static system are fully …
