Topological origin of non-Hermitian skin effect in higher dimensions and uniform spectra
Haiping Hu
The non-Hermitian skin effect is an iconic phenomenon characterized by the aggregation of eigenstates near the system boundaries in non-Hermitian systems. While extensively studied…

Anomalous second-order skin modes in Floquet non-Hermitian systems
Chun-Hui Liu, Haiping Hu, Shu Chen +1
The non-Hermitian skin effect under open boundary conditions is widely believed to originate from the intrinsic spectral topology under periodic boundary conditions. If the eigensp…

Accumulation of scale-free localized states induced by local non-Hermiticity
Cui-Xian Guo, Xueliang Wang, Haiping Hu +1
The bulk states of Hermitian systems are believed insensitive to local Hermitian impurities or perturbations except for a few impurity-induced bound states. Thus, it is important t…
