However, extending the GBZ theory to interacting\n  many-body systems remains an open problem. Here, we consider an\n  interacting non-Hermitian model characterized by a circular GBZ. We\n  show that, based on a GBZ transformation, a quasi-reciprocal\n  many-body Hamiltonian can be constructed which, under periodic\n  boundary conditions (PBC), captures the physics of the original\n  non-Hermitian model under open boundary conditions (OBC).
