Abstract

The effect of mesoscopic fluctuations on the quasiclassical gap in the density of states (DOS) of a diffusive superconductor-normal metal-superconductor (SNS) junction was examined. It was found that these fluctuations smear the gap. The tail of the DOS was due to the states of anomalously localized in the N part of the junction and weakly coupled to the S terminals.
