Representative papers:

[1] Edge states and topological invariants of non-Hermitian systems

Shunyu Yao, Zhong Wang

Phys. Rev. Lett. 121, 086803 (2018)

This paper laid the groundwork for a non-Hermitian band theory, now known as the non-Bloch band theory. In line with this framework, the non-Bloch bulk-boundary correspondence of non-Hermitian systems was proposed. Several terms introduced in this paper, including the "non-Hermitian skin effect" and "generalized Brillouin zone", are now commonly used in non-Hermitian physics. A number of predictions of this theory have been confirmed experimentally.

[2] Non-Hermitian Chern bands  

Shunyu Yao, Fei Song, Zhong Wang

Phys. Rev. Lett. 121, 136802 (2018)

We generalized the non-Hermitian bulk-boundary correspondence and related physics of [1] to higher dimensions.

    

       

[3] Non-Hermitian skin effect and chiral damping in open quantum systems  

Fei Song, Shunyu Yao, Zhong Wang

Phys. Rev. Lett. 123, 170401 (2019)

We applied the non-Bloch band theory to open quantum systems, predicting a new relaxation pattern.

[4] Non-Hermitian bulk-boundary correspondence in quantum dynamics

Lei Xiao, Tianshu Deng, Kunkun Wang, Gaoyan Zhu, Zhong Wang, Wei Yi, Peng Xue

Nat. Phys. 16, 761 (2020)

This work reported the experimental observation of non-Hermitian skin effect. It also confirmed the non-Bloch bulk-boundary correspondence, one of the predictions of non-Bloch band theory.

[5] Simplified Topological Invariants for Interacting Insulators

Zhong Wang and Shou-Cheng Zhang

Phys. Rev. X 2, 031008 (2012)

Topological invariants based on zero-frequency Green's function were proposed. They have later been applied to study topological states in interacting systems.

[6] Equivalent topological invariants of topological insulators

Zhong Wang, Xiao-Liang Qi and Shou-Cheng Zhang

New J. Phys. 12, 065007 (2010)

The precise equivalence was established between the topological invariant based on topological band theory and that based on topological field theory, bridging these two approaches to topological insulators.
