We consider a hybrid structure where a material with Rashba-like spin-orbit coupling is proximity-coupled to a conventional superconductor. We find that the superconducting critical temperature $T_c$ can be tuned by rotating the vector $\vecn$ characterizing the axis of broken inversion symmetry. This is explained by a leakage of $s$-wave singlet Cooper pairs out of the superconducting region, and by conversion of $s$-wave singlets into other types of correlations, among these $s$-wave odd-frequency pairs robust to impurity scattering. These results demonstrate a conceptually different way of tuning $T_c$ compared to the previously studied variation of $T_c$ in magnetic hybrids.

通过反转对称中断轴的旋转来控制超导过渡

我们考虑一种混合结构，其中具有Rashba式自旋轨道耦合的材料接近耦合到常规超导体。我们发现超导临界温度${Ť}_C$可以通过旋转表征破碎反演对称轴的矢量$ \ vecn $进行调整。这是由于泄漏$s$波单重态库珀配对出超导区域，并通过转换 $s$-将单峰转换为其他类型的相关性 $s$杂散鲁棒的双波奇频对。这些结果说明了概念上不同的调优方式${Ť}_C$ 与之前研究的 ${Ť}_C$ 在磁性混合动力车中。
