One-Dimensional Anderson Localization in Certain Correlated Random Potentials
Résumé
We investigate Anderson localization in weak 1D speckle potentials. We show that long-range correlations induce effective mobility edges corresponding to sharp crossovers between regions here localization lengths differ by orders of magnitude. Using perturbation theory, we derive analytical formulas up to two orders beyond Born approximation which prove in excellent agreement with exact numerical calculations. Finally, we analyze our findings in the light of a diagrammatic approach.
