论文摘要
从理论上讲，我们研究了自旋轨道相互作用对二维旋转singlet d-wave超导体中库珀对的对称性的影响。通过分析求解Gor'kov方程获得的异常绿色函数，分析了配对对称性。自旋轨道相互作用诱导均匀超导体中的自旋三个p波配对相关性。由于本地破坏反转对称性，因此在这种超导体的表面上出现了奇数频率自旋 - 三个 - 波配对相关性。我们还讨论了奇数配对相关性，零能量表面结合状态的手性以及异常接近效应之间的密切关系。获得的结果使我们能够设计一个超导体，从而导致强大的近端效应。
We theoretically study the effects of spin-orbit interactions on symmetry of a Cooper pair in a spin-singlet d-wave superconductor in two-dimension. The pairing symmetry is analyzed in terms of the anomalous Green's function which is obtained by solving the Gor'kov equation analytically. A spin-orbit interaction induces a spin-triplet p-wave pairing correlation in a uniform superconductor. An odd-frequency spin-triplet s-wave pairing correlation appears at a surface of such superconductor as a result of breaking inversion symmetry locally. We also discuss a close relationship among the odd-frequency pairing correlation, chirality of surface bound states at the zero energy, and the anomalous proximity effect. The obtained results enable us to design a superconductor which causes the strong anomalous proximity effect.
