Point-gap topology in amorphous non-Hermitian quantum systems
Xue-Min Yang, Deng-Feng Li, Mu Zhou +7
Recent studies have revealed that not only does the correspondence between spectral winding numbers and skin modes break down in non-Hermitian systems, but the energy spectrum itse…

Breakdown of Non-Bloch Bulk-Boundary Correspondence and Emergent Topology in Floquet Non-Hermitian Systems
Hong Wu, Xue-Min Yang, Hui Liu
Topological edge states in gaps of non-Hermitian systems are robust due to topological protection. Using the non-Hermitian Floquet Su-Schrieffer-Heeger model, we show that this rob…
