Universal Spreading Dynamics in Quasiperiodic Non-Hermitian Systems
Ze-Yu Xing, Shu Chen, Haiping Hu
Non-Hermitian systems exhibit a distinctive type of wave propagation, due to the intricate interplay of non-Hermiticity and disorder. Here, we investigate the spreading dynamics in…
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…
Exceptional Non-Abelian Topology in Multiband Non-Hermitian Systems
Cui-Xian Guo, Shu Chen, Kun Ding +1
Defective spectral degeneracy, known as exceptional point (EP), lies at the heart of various intriguing phenomena in optics, acoustics, and other nonconservative systems. Despite e…
Localization, multifractality, and many-body localization in periodically kicked quasiperiodic lattices
Yu Zhang, Bozhen Zhou, Haiping Hu +1
We study the combined effect of quasiperiodic disorder, driven and interaction in the periodically kicked Aubry-André model. In the non-interacting limit, by analyzing the quasiene…
