Metal-Insulator Transition of Disordered Interacting Electrons
arXiv:cond-mat/9805264 · doi:10.1103/PhysRevLett.81.4951
Abstract
We calculate the corrections to the conductivity and compressibility of a disordered metal when the mean free path is smaller than the screening length. Such a condition is shown to be realized for low densities and large disorder. Analysis of the stability of the metallic state reveals a transition to the insulating state in two-dimensions.
