Non-Hermitian skin effect and chiral damping in open quantum systems
Fei Song, Shunyu Yao, Zhong Wang
One of the unique features of non-Hermitian Hamiltonians is the non-Hermitian skin effect, namely that the eigenstates are exponentially localized at the boundary of the system. Fo…

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…

Topological invariants of Floquet systems: General formulation, special properties, and Floquet topological defects
Shunyu Yao, Zhongbo Yan, Zhong Wang
Periodically driven (Floquet) systems have been under active theoretical and experimental investigations. This paper aims at a systematic study in the following aspects of Floquet…
