Non-Hermitian skin effect induced by spatial noncommutativity
Zheng Wei, Su-Peng Kou
In all known schemes for the non-Hermitian skin effect, the non-Hermitian ingredient that drives the skin localization, whether asymmetric hopping or gain and loss, is invariably i…

A Unified Framework for the Non-Hermitian Localization: Boundary-Insensitive Modes and Electric-Magnetic Analogy
Zheng Wei, Ji-Yao Fan, Kui Cao +4
The non-Hermitian skin effect is fundamentally characterized by its sensitivity to boundary conditions, reflected in changes to the energy spectrum and boundary-localized eigenstat…

Magnetic correlations and superconducting pairing near higher-order Van Hove singularities
Zheng Wei, Yanmei Cai, Boyang Wen +1
Higher-order Van Hove singularities in strongly correlated electron systems provide a fertile ground for emergent electronic orders and superconductivity. This study investigates t…
