Invariable mobility edge in a quasiperiodic lattice
Tong Liu, Yufei Zhu, Shujie Cheng +3
In this paper, we study a one-dimensional tight-binding model with tunable incommensurate potentials. Through the analysis of the inverse participation rate, we uncover that the wa…

Generalized Aubry-André self-duality and Mobility edges in non-Hermitian quasi-periodic lattices
Tong Liu, Hao Guo, Yong Pu +1
We demonstrate the existence of generalized Aubry-André self-duality in a class of non-Hermitian quasi-periodic lattices with complex potentials. From the self-duality relations, t…
