用场论方法研究了弱磁杂质势作用下超导体中亚带隙态的分布和谱。这样的状态被发现与空间不均匀的瞬子配置的行动。
A field theoretic approach is developed to investigate the profile and spectrum of subgap states in a superconductor subject to a weak magnetic impurity potential. Such states are found to be associated with spatially inhomogeneous instanton configurations of the action.
