Josephson Current Anomalies in Spin-Orbit Nanowires
IEEE Transactions on Applied Superconductivity(2018)
摘要
We study the anomalous Josephson effect in a nanowire with Rashba spin-orbit interaction and Zeeman spin splitting, contacted with two s-wave superconducting leads with either one or two open conducting channels in the wire. In both cases, we find that the Josephson current is zero at a value φ0 ≠ 0, π of the phase difference between the order parameter of the leads. While in the former case the c...
