Critical Non-Hermitian Skin Effect and Scale-Free Localization Morphing in Bilocally Coupled Hatano-Nelson Chains
Chong Wang, Linhu Li
We investigate the critical non-Hermitian skin effect (CNHSE) and the coupling-driven morphing of scale-free localization (SFL) in two Hatano-Nelson chains coupled locally at two b…

Milad Jangjan, Linhu Li, Longwen Zhou +1
We theoretically investigate a one-dimensional trimerized Su--Schrieffer--Heeger chain with three sublattices per unit cell subjected to a nonreciprocal Rashba spin-orbit coupling.…
Anyon-induced non-Hermitian topological phases
Yi-An Wang, Kun Ding, Linhu Li
We show that anyonic exchange statistics can activate non-Hermitian point-gap topology in models that are topologically trivial in its absence. The emergent topology oscillates mor…
Boundary Floquet Control of Bulk non-Hermitian Systems
Yu-Min Hu, Yu-Bo Shi, Linhu Li +5
Boundary perturbations are generally irrelevant for bulk properties in the thermodynamic limit, as they are edge-confined and subextensive. We show that this expectation breaks dow…
Anyon-Induced Criticality and Dynamical Stability in Non-Hermitian Many-Body Systems
Yi Qin, Yee Sin Ang, Linhu Li +1
We show that anyonic statistics fundamentally reshapes non-Hermitian many-body physics by intrinsically breaking pseudo-Hermiticity, leading to a unique real-complex spectral trans…
Controlling Liouvillian topological phases via Hamiltonian band topology under chiral symmetry
Shu Long, Hong-Sen Yin, Chao Yang +3
We establish a direct connection between Hamiltonian band topology and the Liouvillian spectral winding of open quantum systems with quadratic dissipations. This allows the band to…

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…
