论文摘要
我们研究了自旋轨道偶联对超导体附着的正常金属中接近诱导的超导性的影响。具体而言，我们考虑了一个异质结构，其中界面的存在产生了Rashba旋转轨道耦合。这些系统中诱导的超导性的性质在哈密顿式形式主义中得到了解决。我们发现，旋转轨道耦合会诱导单线和三重态配对的混合物，在特定的情况下，可能会出现奇数频率，甚至奇偶校验，旋转三重态。我们还解决了杂质散射对诱导对的影响，并讨论了我们的结果，这些异质结构由带有旋转摩托锁的材料组成。
We investigate the effect of spin orbit coupling on proximity induced superconductivity in a normal metal attached to a superconductor. Specifically, we consider a heterostructure where the presence of interfaces gives rise to a Rashba spin orbit coupling. The properties of the induced superconductivity in these systems are addressed within the tunneling Hamiltonian formalism. We find that the spin orbit coupling induces a mixture of singlet and triplet pairing and, under specific circumstances, an odd frequency, even parity, spin triplet pairs can arise. We also address the effect of impurity scattering on the induced pairs, and discuss our results in context of heterostructures consisting of materials with spin-momentum locking.
