Josephson dc Current through T-Shaped Double-Quantum-Dots Hybridized to Majorana Nanowires

We study quantum interference effects on Josephson current in T-shaped double dots (TDQDs) with one of them (the central dot) is sandwiched between the left and right topological superconductor nanowires hosting Majorana bound states (MBSs). find that current’s magnitude suppressed by inter-dot coupling induces effect, unchanged jump at particular phase difference two from which effect arises. The remains as a sinusoidal function respective to presence but significant reduction. broad peak curve versus QDs’ levels are split different ways depending configurations latter. also impacts non-z-axial direction magnetic field, bending angle direct hybridization amplitude MBSs all depend arrangement energy levels.
