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…
From Ergodicity to Many-Body Localization in a One-Dimensional Interacting Non-Hermitian Stark System
Jinghu Liu, Zhihao Xu
Recent studies on disorder-induced many-body localization (MBL) in non-Hermitian quantum systems have attracted great interest. However, the non-Hermitian disorder-free MBL still n…
Characterizations for the existence of traces of first-order Sobolev spaces on hyperbolic fillings
Manzi Huang, Zhihao Xu
In this paper, we study the existence of traces for Sobolev spaces on the hyperbolic filling of a compact metric space equipped with a doubling measure. Given a suitable me…
Dynamical evolution in a one-dimensional incommensurate lattice with symmetry
Zhihao Xu, Shu Chen
We investigate the dynamical evolution of a parity-time () symmetric extension of the Aubry-André (AA) model, which exhibits the coincidence of a localization-delocal…
Topological Bose-Mott insulators in one-dimensional non-Hermitian superlattices
Zhihao Xu, Shu Chen
We study the topological properties of Bose-Mott insulators in one-dimensional non-Hermitian superlattices, which may serve as effective Hamiltonians for cold atomic optical system…
Fate of zero modes in a finite Su-Schrieffer-Heeger Model with Symmetry
Zhihao Xu, Rong Zhang, Shu Chen +2
Due to the boundary coupling in a finite system, the zero modes of a standard Su-Schrieffer-Heeger (SSH) model may deviate from exact-zero energy. A recent experiment has shown tha…
