Realistic model of correlated disorder and Anderson localization
Abstract
A conducting 1D line or 2D plane inside (or on the surface of) an insulator is considered.Impurities displace the charges inside the insulator. This results in a long-range fluctuating electric field acting on the conducting line (plane). This field can be modeled by that of randomly distributed electric dipoles. This model provides a random correlated potential with <U(r)U(r+k)> decaying as 1/k . In the 1D case such correlations give essential corrections to the localization length but do not destroy Anderson localization.
