非中心对称超导体中库珀对宇称混合的非守恒探测

Unambiguous probe of parity-mixing of Cooper pairs in noncentrosymmetric superconductors

Satoshi Fujimoto

摘要:

我们提出了一个实验方案来检测明确的奇偶性混合的库珀对在非中心对称的超导体,它利用交叉Andreev反射过程之间的两个相反的自旋极化正常金属引线和非中心对称的超导体。结果表明,非局域电导具有明显的库珀对宇称破缺特征,因此,可以作为宇称混合的直接探针。

英文摘要:

We propose an experimental scheme to detect unambiguously parity-mxing of Cooper pairs in noncentrosymmetric superconductors, which utilizes crossed Andreev reflection processes between two oppositely spin-polarized normal metal leads and a noncentrosymmetric superconductor. It is demonstrated that a non-local conductance exhibits a clear signature of parity breaking of Cooper pairs, and thus, can be a direct probe for the parity-mixing.
