Non-Hermitian entanglement dip from scaling-induced exceptional criticality
Sirui Liu, Hui Jiang, Wen-Tan Xue +4
It is well established that the entanglement entropy of a critical system generally scales logarithmically with system size. Yet, in this work, we report a new class of non-Hermiti…

Phase-space Generalized Brillouin Zone for spatially inhomogeneous non-Hermitian systems
Qingya Li, Hui Jiang, Ching Hua Lee
The generalized Brillouin zone (GBZ) has been highly successful in characterizing the topology and band structure of non-Hermitian systems. However, its applicability has been chal…
