Tunable 0-\pi transitions and high harmonics current-phase relation in Josephson junctions with multi-orbital noncentrosymmetric superconductors

We study the Josephson current in the three-orbital NCS-NCS Josephson junctions. Then we focus on the interorbital topological superconductivity. We find that high harmonics term in the current phase relation can be dominant at the low temperature when the mismatch of the Fermi surfaces in three-orbital NCSs occurs as shown in Figure 1. We also show the anomalous temperature dependence of Josephson current when the high harmonics terms appear at low temperature.
