Impurity-induced loss bursts from anomalous scale-free localization in a non-Hermitian dissipative lattice
Hui Liu, Zhihao Xu
We identify anomalous scale-free localization and the associated impurity-induced loss bursts in a non-Hermitian dissipative cross-stitch lattice. By a local basis rotation, the mo…
Even--odd classification of reentrant topology in a Su--Schrieffer--Heeger chain with integer-power quasiperiodic hopping
Yusheng Niu, Hui Liu, Zhihao Xu
We investigate reentrant topology in a one-dimensional Su--Schrieffer--Heeger chain with integer-power quasiperiodically modulated intracell hopping. The modulation is controlled b…
Exceptional-point-constrained locking of boundary-sensitive topological transitions in chiral non-Hermitian SSH-type lattices
Huimin Wang, Yanxin Liu, Zhijian Li +1
Topological transitions in non-Hermitian systems are generally boundary sensitive: a point-gap winding transition under periodic boundary condition (PBC) and a non-Bloch bulk real-…
Exact multiple anomalous mobility edges in a flat band geometry
Zhanpeng Lu, Hui Liu, Yunbo Zhang +1
Anomalous mobility edges(AMEs), separating localized from multifractal critical states, represent a novel form of localization transition in quasiperiodic systems. However, quasi-p…
Fibonacci-Modulation-Induced Multiple Topological Anderson Insulators
Ruijiang Ji, Zhihao Xu
Topological Anderson insulators (TAIs) provide a mechanism for topological phase transitions in disordered systems and have implications for quantum material design. In this work,…
Fate of localization features in a one-dimensional non-Hermitian flat-band lattice with quasiperiodic modulations
Hui Liu, Zhanpeng Lu, Xu Xia +1
We investigate the influence of quasiperiodic modulations on one-dimensional non-Hermitian diamond lattices with an artificial magnetic flux that possess flat bands. Our study…
