Impurity band in clean superconducting weak links

Abstract

Weak impurity scattering produces a narrow band with a finite density of states near the phase difference $\varphi =\pi$ in the mid-gap energy spectrum of a macroscopic superconducting weak link. The equivalent distribution of transmission coefficients of various cunducting quantum channels is found.
