Non-Hermitian Chern bands
Shunyu Yao, Fei Song, Zhong Wang
The relation between chiral edge modes and bulk Chern numbers of quantum Hall insulators is a paradigmatic example of bulk-boundary correspondence. We show that the chiral edge mod…

Edge states and topological invariants of non-Hermitian systems
Shunyu Yao, Zhong Wang
The bulk-boundary correspondence is among the central issues of non-Hermitian topological states. We show that a previously overlooked `non-Hermitian skin effect' necessitates rede…
