Numerical Calculation of Conductivity of Disordered Systems

Abstract

The dc-conductivity of the two and three dimensional Anderson model is studied numerically using the equation of motion method. From the disorder dependence of the conductivity in the center of the band a minimum metallic conductivity is estimated. Its numerical value is 0.2 ± 0.1 e2/ħ for the square lattice and 0.05±0.02 e2/ħa for the simple cubic lattice.
