Anderson localization in a correlated landscape near the band edge

摘要

We study the Anderson localization in a potential landscape with long-range power-law correlations in one dimension. We find that, for energies E close to the band edge of the unperturbed energy band, the presence of correlations makes the states more strongly localized, compared with the uncorrelated case, and a novel scaling of the localization length appears.
