WebThe effect of non-Hermiticity in band topology has sparked many discussions on non-Hermitian topological physics. It has long been known that non-Hermitian Hamiltonians can exhibit real energy spectra under the condition of parity-time (PT) symmetry—commonly implemented with balanced loss and gain—but only when non-Hermiticity is relatively ...
