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 $sin p_{x} + i sin p_{y}$ -wave and $sin p_{x} - i sin p_{y}$ -wave superconductors are clarified in the vortex lattice state. We also discuss the winding $\mp 3$ case of the $sin (p_{x} + p_{y}) \pm i sin (- p_{x} + p_{y})$ -wave superconductivity.
