 abstract = {We model a one-dimensional current-driven interacting disordered system
through a non-Hermitian Hamiltonian with asymmetric hopping and study
the entanglement properties of its eigenstates. In particular, we
investigate whether a many-body localizable system undergoes a
transition to a current-carrying nonequilibrium steady state under the
drive and how the entanglement properties of the quantum states change
across the transition. We also discuss the dynamics, entanglement
growth, and long-time fate of a generic initial state under an
appropriate time evolution of the system governed by the non-Hermitian
Hamiltonian. Our study reveals rich entanglement structures of the
eigenstates of the non-Hermitian Hamiltonian. We find transition between
current-carrying states with volume-law to area-law entanglement
entropy, as a function of disorder and the strength of the non-Hermitian
term.},
