Metal-Insulator Transition of Disordered Interacting Electrons
Qimiao Si, C. M. Varma
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.
