Fluctuations of Transmission Distribution in Disordered Conductors

Abstract

We developed a microscopic approach to calculate the sample-to-sample fluctuations of transmission distribution in disordered conductors. This bridges between Green's function and random matrix theories of quantum transport. The results obtained show that the correlations of transmission eigenvalues obey universal Dyson statistics at small separations between eigenvalues being non-universal otherwise. The results facilitate an easy computation of different physical quantities and impose important constrains on a future imaginable theory of quantum transport.
