Abstract

By considering a pure d_xy-wave order parameter (OP), the Bogoliubov-de Gennes equations for a pure d_xy-wave superconductor is reformulated into a full differential form. We also derive the self-consistent equation for the OP, which is tested by the bulk state and the surface problem. Very importantly, it is shown that the new set of equations has a constrained gauge invariance.
