Entanglement Phase Transition in Chaotic non-Hermitian Systems
In chaotic non-Hermitian spin chains satisfying a commutation condition, rising dissipation rate drives a volume-to-area law transition in steady-state entanglement entropy, with the complex gap showing oscillations from level crossings before gapping.
