Vertex Corrections in the Spin-fluctuation-induced Superconductivity
arXiv:cond-mat/9910154 · doi:10.1143/JPSJ.69.190
Abstract
We evaluate vertex corrections to on the basis of the antiferromagnetic spin-fluctuation model of the high- superconductivity. It is found that the corrections are attractive in the channel, and they become appreciable as we go through an intermediate-coupling regime of K, the maximum attainable in the one-loop Éliashberg calculation.
