Influence of spin-orbit coupling on differential conductance of normal metal/ferromagnetic p wave superconductor junctions

Abstract The extended Blonder–Tinkham–Klapwijk model is applied to studying tunneling conductance in normal metal/ferromagnetic p wave superconductor junctions. It is found that the spin–orbit scattering at the interfaces significantly affects the tunneling conductance. The interface spin–orbit coupling (SOC) suppresses the split conductance peaks in the N/ferromagnetic p x wave superconductor junction and enhances the zero-bias conductance dip (ZBCD) of p y wave superconductor junction. The SOC gives rise to the asymmetry of the conductance spectrum in the ferromagnetic p x  + p y wave superconductor junctions.
