Abstract

We use a detailed microscopic analysis to study electron transport in normal diffusive conductors in the presence of proximity induced superconducting correlation. In the case of transparent barriers, superconducting correlations and electrical field can penetrate causing a whole range of novel nonequilibrium effects. These effects are explained by the introduction of a second, correlated density of states. Our results are fully consistent with recent experimental findings.
