Unambiguous probe of parity mixing of Cooper pairs in noncentrosymmetric superconductors

We propose an experimental scheme to detect unambiguously parity mixing 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 nonlocal conductance exhibits a clear signature of parity breaking of Cooper pairs and, thus, can be a direct probe of the parity mixing.
