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…
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…
Emergence of multifractality through cascade-like transitions in a mosaic interpolating Aubry-André-Fibonacci chain
Qi Dai, Zhanpeng Lu, Zhihao Xu
In this paper, we explore the localization features of wave functions in a family of mosaic quasiperiodic chains obtained by continuously interpolating between two limits: the mosa…
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…
Exact Mobility edges and topological Anderson insulating phase in a slowly varying quasiperiodic model
Zhanpeng Lu, Zhihao Xu, Yunbo Zhang
We uncover the relationship of topology and disorder in a one-dimensional Su-Schrieffer-Heeger chain subjected to a slowly varying quasi-periodic modulation. By numerically calcula…
Predicting Large-Chern-Number Phases in a Shaken Optical Dice Lattice
Shujie Cheng, Honghao Yin, Zhanpeng Lu +3
With respect to the quantum anomalous Hall effect (QAHE), the detection of topological nontrivial large-Chern-number phases is an intriguing subject. Motivated by recent research o…
