Vortex structure in chiral p-wave superconductors

Abstract

We investigate the vortex structure in chiral p-wave superconductors by the Bogoliubov-de Gennes theory on a tight-binding model. We calculate the spatial structure of the pair potential and electronic state around a vortex, including the anisotropy of the Fermi surface and superconducting gap structure. The differences of the vortex structure between $\sin p_x+\mathrm{i}\sin p_y$-wave and $\sin p_x-\mathrm{i}\sin p_y$-wave superconductors are clarified in the vortex lattice state. We also discuss the winding $\mp 3$ case of the $\sin (p_x+p_y)\pm \mathrm{i}\sin (-p_x+p_y)$-wave superconductivity.
