Quantum walks in commensurate off-diagonal Aubry-André-Harper model
Li Wang, Na Liu, Shu Chen +1
Due to the topological nature of Aubry-André-Harper (AAH) model, exotic edge states have been found existing in one-dimensional periodic and quasiperiodic lattices. In this article…

Quantum walks accompanied by spin flipping in one-dimensional optical lattices
Li Wang, Na Liu, Shu Chen +1
We investigate continuous-time quantum walks of two fermionic atoms loaded in one-dimensional optical lattices with on-site interaction and subjected to a Zeeman field. The quantum…

Preparation of stable excited states in an optical lattice via sudden quantum quench
Li Wang, Yajiang Hao, Shu Chen
We study how stable excited many-body states of the Bose-Hubbard model, including both the gas-like state for strongly attractive bosons and bound cluster state for repulsive boson…
