Impurity-induced topological decomposition
Tianxing Shi, Chuhang Zhang, Liang Jin +1
Controlling topological phases is a central goal in quantum materials and related fields, enabling applications such as robust transport and programmable edge states. Here we uncov…
Size-dependent critical localization
Hui-Qiang Liang, Linhu Li, Guo-Fu Xu
Studying critical states in quasiperiodic systems is of great importance in localization physics. Previously identified critical states share a common characteristic: they exhibit…
Intrinsic-perturbation induced anomalous higher-order boundary states in non-Hermitian systems
Hui-Qiang Liang, Zuxuan Ou, Linhu Li +1
The behavior of higher-order boundary states in non-Hermitian systems is elusive and thereby finding the mechanism behind these states is both essential and significant. Here, we u…
Size-Dependent Skin Effect Transitions in Weakly Coupled Non-Reciprocal Chains
Yixuan Li, Linhu Li, Zhihao Xu
Non-Hermitian systems exhibit unique boundary phenomena absent in their Hermitian counterparts, most notably the non-Hermitian skin effect (NHSE). In this work, we explore a lattic…
Anisotropic-scaling localization in higher-dimensional non-Hermitian systems
Zuxuan Ou, Hui-Qiang Liang, Guo-Fu Xu +1
Spatial localization of quantum states is one of the focal points in condensed matter physics and quantum simulations, as it signatures profound physics such as nontrivial band top…
Anderson-skin dualism: A boundary-dependent effect in non-Hermitian disordered coupled systems
Shan-Zhong Li, Linhu Li, Shi-Liang Zhu +1
We report a novel localization phenomenon that emerges in non-Hermitian and quasiperiodic coupled systems, which we dub ``Anderson-Skin (AS) dualism". The emergence of AS dualism i…
