Skyrmion control of Majorana states in planar Josephson junctions

Planar Josephson junctions provide a versatile platform, alternative to the nanowire-based geometry, for generation of Majorana bound states, due additional phase tunability topological superconductivity. The proximity induction chiral magnetism and superconductivity in two-dimensional electron gas showed remarkable promises manipulate Here, we consider junction involving skyrmion crystal show that skyrmions can create control states without requirement an intrinsic Rashba spin-orbit coupling. Interestingly, our geometry are realized robustly at zero difference junction. radius, being externally tunable by magnetic field or anisotropy, brings unique feature states.
