论文摘要
我们表明，常规超导体中的稀释磁杂质使超导性的奇数成分产生，在宽大超导体间隙内形成的Yu-Shiba-Rusinov带中表现出来。我们的结果是在动态平均场理论中求解的通用模型中获得的。通过利用疾病分析和对单个杂质的极限，我们能够提供一般表达式，可用于从扫描隧道测量中明确提取奇数超导函数。
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.
