Abstract

We find that on short-length scales the phase of the amplitude reflection coefficient is strongly correlated with the random potential in the one-dimensional disordered conductors. This correlation results in suppression of the large conductance G(L) fluctuation making <G(L)> finite. We predict a minimum in <G(L)> vs L.
