Coherent transport in a normal diffusive wire between two reservoirs

Abstract

We develop a detailed analysis of electron transport in normal diffusive con- ductors in the presence of proximity induced superconductivity. A rich structure of temperature and energy dependencies for the system condcutcance, density of states and related quantities was found and explained. If the nor- mal conductor forms a loop its conductance changes h/2e-periodically with the magnetic flux inside the loop. The amplitude of these conductance oscillations shows a reentrant behavior and decays as 1/T at high T
