摘要：

We study the localization properties of a one-dimensional incommensurate potential in the full quantum regime. In the system under consideration, and for amplitudes of the potential that are not too weak, the spectrum contains both localized and extended states, with one or more mobility edges. We show how these properties can be experimentally studied through the diffusion of wave packets in a one-dimensional incommensurate optical lattice.
