The emergence of equilibrium statistical mechanics from "quantum chaos" in closed (unitary) quantum systems has received considerable attention in recent decades, with many of its outstanding achievements inspired and aided by random matrix theory. It is natural to ask how the lessons we have learned from this venture translate to open quantum systems, which are characterized by non-Hermitian operators. I will discuss how two fundamental characteristics of Hermitian quantum chaos, volume-law entanglement entropy and the eigenstate thermalization hypothesis, are significantly modified in the presence of non-Hermiticity. Based on PRL 130, 010401 and arXiv:2303.03448.
