Conductance distribution in disordered quantum wires: Crossover between the metallic and insulating regimes
We calculate the distribution of the conductance P(g) for a
quasi-one-dimensional system in the metal to insulator crossover regime, based
on a recent analytical method valid for all strengths of disorder. We show the
evolution of P(g) as a function of the disorder parameter from a insulator to a
metal. Our results agree with numerical studies reported on this problem, and
with analytical results for the average and variance of g.Comment: 8 pages, 5 figures. Final version (minor changes
