论文摘要
我们在存在外部应用的采地和超电流的情况下研究了常规超导电线之间的约瑟夫森连接。我们证明，临界约瑟夫森电流和连接的电流相关关系取决于所施加的Zeeman场和超电流的相对方向。约瑟夫森电流的可控性依赖于高磁场中常规超导性的稳定，这是由于在费米水平上恢复了相反的相反的自旋投影共振。我们断言，我们的结果可以导致新型超导电子产品的发展。
We investigate Josephson junctions among conventional superconducting wires, in the presence of externally applied Zeeman fields and supercurrents. We demonstrate that the critical Josephson current and the current-phase relation of the junction depends on the relative orientation of the applied Zeeman fields and supercurrents. The controllability of the Josephson current relies on the stabilization of conventional superconductivity in high magnetic fields, due to the restoration of the opposite momentum opposite spin projection resonance at the Fermi level. We assert that our results can lead to the development of novel superconducting electronics.
