Anderson Localization in 1D Systems with Correlated Disorder

By Alexander Croy, Philipp Cain and Michael Schreiber


Anderson localization has been a subject of intense studies for many years. In this context, we study numerically the influence of long-range correlated disorder on the localization behavior in one dimensional systems. We investigate the localization length and the density of states and compare our numerical results with analytical predictions. Specifically, we find two distinct characteristic behaviors in the vicinity of the band center and at the unperturbed band edge, respectively. Furthermore we address the effect of the intrinsic short-range correlations.Comment: 5 pages, 5 figure
