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…
Pseudo-critical localization
Hui-Qiang Liang, Linhu Li, Guo-Fu Xu
We uncover a novel localization phenomenon, termed pseudo-critical localization, in non-Hermitian critical systems. This phenomenon is induced by the synergistic interplay between…
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…
Concurrent Skin-scale-free Localization and Criticality under Möbius Boundary Conditions in a Non-Hermitian Ladder
Shu Long, Linhu Li
Non-Hermitian systems possess exotic localization phenomena beyond their Hermitian counterparts, exhibiting massive accumulation of eigenstates at the system boundaries with differ…
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…
Many-body critical non-Hermitian skin effect
Yi Qin, Yee Sin Ang, Ching Hua Lee +1
Criticality in non-Hermitian systems unveils unique phase transitions and scaling behaviors beyond Hermitian paradigms, offering new insights into the interplay between gain/loss,…
Inter-species topological phases via a dynamical gauge field
Zhoutao Lei, Linhu Li
We uncover a class of inter-species topological phases in a one-dimensional lattice, loaded with two species of non-identical particles interacting via a dynamical gauge field (DGF…
