Non-Hermitian topological systems with eigenvalues that are always real
The 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...
