Deterministic bulk-boundary correspondences for skin and edge modes in a general two-band non-Hermitian system
In isolated Hermitian systems, the bulk-boundary correspondence is generally thought of as a compelling principle guiding the occurrence of robust edge states through the topological invariants of the bulk. However, in open non-Hermitian systems that support non-Hermitian skin effects, the universal...
