The random distribution of site energies is assumed to have a power spectrum S(k)similar to1/k(alpha) with alpha>0. de Moura and Lyra [Phys. Rev. Lett. 81, 3735 (1998)10.1103/Phys. Rev. Lett.81.3735] predicted that this model supports a phase of delocalized states at the band center, separated from localized states by two mobility edges, provided alpha>2. We find clear signatures of Bloch-like oscillations of an initial Gaussian wave packet between the two mobility edges and determine the bandwidth of extended states, in perfect agreement with the zero-field prediction.engjournal articlehttp://dx.doi.org/10.1103/PhysRevLett.91.197402http://journals.aps.org/open access538.9Metal-Insulator-TransitionAnderson ModelMobility EdgeLocalizationSuperlattices.
