Abstract
We investigate the effects of scale-free disorder on the metal-insulator transition. Scale-free disorder is characterized by an autocorrelation function decaying asymptotically as r(-alpha). We study the dependence of the localization-length exponent v on the correlation-strength exponent a. We find that for fixed disorder W, there is a critical alpha(c), such that for alpha < alpha(c), we have v = 2/alpha while for alpha > alpha(c), nu retains the value of the uncorrelated system in accordance with the extended Harris criterion. At the band center, nu is independent of a but equal to that of the uncorrelated system.
