Author(s): Rafael D. Soares, Matteo Brunelli, and Marco Schirò While nonreciprocal couplings are ubiquitous in classical systems, their impact on quantum many-body criticality and entanglement remains largely unexplored. Using exact numerical simulations, we study an interacting fermionic chain subject to nonreciprocal gain and loss. We show that the interplay … [Phys. Rev.
