概要
- 論文の詳細を見る
On the basis of de Gennes' formalism, it is shown that the effect of the long-time-tail in the "force correlation function", due to the diffusion process of the magnetization of conduction electrons (for the correlation function of the time-reversal operator $K$), gives rise to an excess suppression of the superconducting transition temperature $T_{\text{c}}$ of conventional superconductors with magnetic impurities. The suppression of $T_{\text{c}}$ is prominent in the one-dimensional case, while those in two- and three-dimensional cases are almost invisible for realistic values of parameter for the quantum correction.
