| Summary: |
We study the current statistics in normal diffusive conductors in contact with a superconductor. Using an extension of the Keldysh Green s function method we are able to find the full distribution of charge transfers for all temperatures and voltages. For the non-Gaussian regime, we show that the equilibrium current fluctuations are enhanced by the presence of the superconductor. We predict an enhancement of the nonequilibrium current noise for temperatures below and voltages of the order of the Thouless energy ETh=D/L². Our calculation fully accounts for the proximity effect in the normal metal and agrees with experimental data.
