Quantum walks in the commensurate off-diagonal Aubry-André-Harper model
Quantum walks in the commensurate off-diagonal Aubry-André-Harper model
Due to the topological nature of the Aubry-Andr\'e-Harper (AAH) model, interesting edge states have been found existing in one-dimensional periodic and quasiperiodic lattices. In this article, we investigate continuous-time quantum walks of identical particles initially located on either edge of commensurate AAH lattices in detail. It is shown that the …
