Influence of Frustration Effect on Return Current of Tunnel Josephson Junction Between Single-Band and Multi-band Superconductors
摘要
In this work, we study the return current of tunnel Josephson junctions, when one of electrode is the single-band and another is the multi-band superconductors. It is shown that the behavior of the return current of such junctions is determined by the ratio of the supercurrent amplitudes of the different channels in current-phase relation.
