Abstract

The self-consistent current relaxation theory for the Anderson transition is generalized to include quantum interference effects. The influence of long-ranged potential fluctuations as opposed to short-ranged ones is discussed and for dimensionality d>2 a crossover for the dynamical conductivity from a regime with Wegner scaling to one with the scaling laws for classical percolation is found. For d=2 an abrupt transition from strong to extremely weak localization is obtained.
