Predicted mobility edges in one-dimensional incommensurate optical lattices: an exactly solvable model of anderson localization

Localization properties of noninteracting quantum particles in one-dimensional incommensurate lattices are investigated with an exponential short-range hopping that is beyond the minimal nearest-neighbor tight-binding model. Energy dependent mobility edges are analytically predicted in this model an...
