Superconducting diode effect due to magnetochiral anisotropy in topological insulators and Rashba nanowires

The critical current of a superconductor can depend on the direction flow due to magnetochiral anisotropy when both inversion and time-reversal symmetry are broken, an effect known as superconducting (SC) diode effect. Here, we consider one-dimensional (1D) systems in which superconductivity is induced via proximity In topological insulator Rashba nanowires, SC magnetic field applied along spin-polarization axis perpendicular nanowire provides measure breaking presence superconductor. Furthermore, strong dependence additional component parallel well position chemical potential be used detect that device region parameter space where phase transition expected arise.
