Correlated transport in silicene-based Josephson junctions

We theoretically investigate the effects of exchange splitting, electric field and strain on the supercurrent in silicene-based Josephson junctions. It is observed that a $0\ensuremath{-}\ensuremath{\pi}$ transition is induced by the exchange splitting, and the critical supercurrent at the transition point is nonvanishing. Owing to the unique buckling structure of silicene, the supercurrent can be effectively controlled by the electric field. For the strain dressed supercurrent, it is revealed that the current-phase relation is profoundly influenced by the strain, and the supercurrent exhibits a switch effect with increasing the strength of strain. These findings will potentially provide some intriguing insights into the correlated transport in silicene-based Josephson junctions.
