Coexistence of ergodic and weakly ergodic states in finite-height Wannier-Stark ladders

Xingbo Wei, Liangqing Wu, Kewei Feng +2

We investigate a single-particle in one-dimensional Wannier-Stark ladders with either a linear potential or a mosaic potential with spacing $\hat{I}º=2$. In both cases, we exactly determ…
