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…

Reentrant Localization Transitions in a Topological Anderson Insulator: A Study of a Generalized Su-Schrieffer-Heeger Quasicrystal
Zhanpeng Lu, Yunbo Zhang, Zhihao Xu
We study the topology and localization properties of a generalized Su-Schrieffer-Heeger (SSH) model with a quasi-periodic modulated hopping. It is found that the interplay of off-d…

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…
