摘要：

We study the paraconductivity in an impure unconventional superconductor. We find that the Azlamazov and Larkin term in three dimensions consists of two contributions, one involving a sum of s-wave-like terms, and an extra piece involving differences of different coherence lengths. In two dimensions the result is found to be universal, being proportional to the number of components of the order parameter. The Maki-Thompson terms are found to be less divergent and hence negligible due to pair-breaking effects. © 1990 The American Physical Society.
