摘要:

我们表明,在传统的超导体中的稀磁杂质起源于超导性的奇频分量,表现在Yu-Shiba-Rusinov带内形成的散装超导能隙。我们的结果是在动力学平均场论求解的一般模型中得到的。通过利用一个无序分析和限制到一个单一的杂质,我们能够提供一般的表达式,可用于明确提取的奇频超导功能从扫描隧道测量。

英文摘要:

We show that dilute magnetic impurities in a conventional superconductor give origin to an odd-frequency component of superconductivity, manifesting itself in Yu-Shiba-Rusinov bands forming within the bulk superconducting gap. Our results are obtained in a general model solved within the dynamical mean field theory. By exploiting a disorder analysis and the limit to a single impurity, we are able to provide general expressions that can be used to extract explicitly the odd-frequency superconducting function from scanning tunneling measurements.
