We argue that parametrically strong enhancement of a thermoelectric current can be observed in conventional superconductors doped by magnetic impurities. This effect is caused by the violation of the symmetry between electronlike and holelike excitations due to formation of subgap bound Andreev states in the vicinity of magnetic impurities. We develop a quantitative theory of this effect and demonstrate that it can be detected in modern experiments.
我们认为，在掺杂磁性杂质的传统超导体中，可以观察到热电流的参数增强。这种效应是由于在磁性杂质附近形成亚带隙束缚安德烈夫态，导致电子激发和空穴激发之间的对称性被破坏而引起的。我们发展了这种效应的定量理论，并证明可以在现代实验中检测到它。
