Abstract
Effects of tunneling motion of atoms characteristic in glass systems on superconductivity is theoretically studied. The pair-breaking mechanism of superconductivity proportional to [ln(7/D)]2 is derived in the fourth order of the Coulomb interaction between conduction electrons and atoms, where T is the temperature and D is the band width. We propose that the pair-breaking mechanism is an origin of the universal absence of the Maki term in the paraconductivity in amorphous superconductors.
