and anti- phase transitions in a trimerized Su--Schrieffer--Heeger chain with nonreciprocal Rashba spin-orbit coupling
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.…
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…
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…
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…
Topological and fractal defect states in non-Hermitian lattices
Gan Liang, Linhu Li
Higher dimensions provide fertile ground for diverse topological phases and their associated localization phenomena, thanks to the rich geometric features of boundaries and defects…
Topological phases of commensurate or incommensurate non-Hermitian Su-Schrieffer-Heeger lattices
Milad Jangjan, Linhu Li, Luis E. F. Foa Torres +1
We theoretically investigate topological features of a one-dimensional Su-Schrieffer-Heeger lattice with modulating non-Hermitian on-site potentials containing four sublattices per…
Observation of scale-free localized states induced by non-Hermitian defects
Xinrong Xie, Gan Liang, Fei Ma +7
Wave localization is a fundamental phenomenon that appears universally in both natural materials and artificial structures and plays a crucial role in understanding the various phy…
Topologically compatible non-Hermitian skin effect
Rijia Lin, Linhu Li
The bulk-boundary correspondence (BBC) relates in-gap boundary modes to bulk topological invariants. In certain non-Hermitian topological systems, conventional BBC becomes invalid…
A brief review of hybrid skin-topological effect
Weiwei Zhu, Linhu Li
The finding of non-Hermitian skin effect has revolutionized our understanding of non-Hermitian topological phases, where the usual bulk-boundary correspondence is broken and new to…
