Vortex Charging Effect in a Chiral $p_x\pm i{p}_y$-Wave Superconductor

Abstract

Quasiparticle states around a single vortex in a $p_x\pm i{p}_y$-wave superconductor are studied on the basis of the Bogoliubov-de Gennes (BdG) theory, where both charge and current screenings are taken into account. Due to the violation of time reversal symmetry, there are two types of vortices which are distinguished by their winding orientations relative to the angular momentum of the chiral Cooper pair. The BdG solution shows that the charges of the two types of vortices are quite different, reflecting the rotating Cooper pair of the $p_x\pm i{p}_y$-wave paring state.
