Superconductivity in a quasi-one-dimensional metal with impurities

The influence of ordinary impurities on the superconducting transition is studied in a quasi-one-dimensional metal. Superconductivity is considered in a self-consistent field (BCS) approximation. It is shown that, depending on the properties of the electron-electron interaction, singlet or triplet superconductivity may appear. Impurities do not influence the critical temperature in the singlet case but destroy the triplet superconductivity. The concentration dependence of the critical temperature in the triplet case is in qualitative agreement with the experimental results for irradiated quasi-1d superconductors; therefore triplet superconductivity may be supposed in these systems. The superconducting current is calculated in the vicinity of the transition temperature and hence the longitudinal dielectric constant for not too high frequencies.
