自旋三重态超导体的电导谱

Conductance Spectroscopy of Spin-triplet Superconductors

Yasuhiro Asano, Yukio Tanaka, Alexander A. Golubov, Satoshi Kashiwaya

摘要:

我们提出了一个新的实验,以确定超导体的对称性的基础上的理论结果的微分电导的正常金属连接到超导体。来自超导体的邻近效应改变了远程电流的电导,这显著取决于配对对称性:自旋单重态或自旋三重态。电导的明显差异可以通过正常金属中的库珀对相对于频率的对称性来解释。在自旋三重态情况下,由于库珀对的奇频对称性,实现了反常输运。

英文摘要:

We propose a novel experiment to identify the symmetry of superconductivity on the basis of theoretical results for differential conductance of a normal metal connected to a superconductor. The proximity effect from the superconductor modifies the conductance of the remote current depending remarkably on the pairing symmetry: spin-singlet or spin-triplet. The clear-cut difference in the conductance is explained by symmetry of Cooper pairs in a normal metal with respect to frequency. In the spin-triplet case, the anomalous transport is realized due to an odd-frequency symmetry of Cooper pairs.
