Interplay between Vorticity and Chirality inside the Vortex Core in Chiral p-Wave Superconductors
Abstract
The vortex core in chiral p-wave superconductors exhibits various properties owing to the interplay between the vorticity and chirality inside the vortex core. In the chiral p-wave superconductors, the site-selective nuclear spin-lattice relaxation rate T1^{-1} is theoretically studied inside the vortex core within the framework of the quasiclassical theory of superconductivity. T1^{-1} at the vortex center depends on the sense of the chirality relative to the sense of the magnetic field. The effect of a tilt of the magnetic field upon T1^{-1} is investigated. The effect of the anisotropy in the superconducting gap and the Fermi surface is then investigated. The result is expected to be experimentally observed as a sign of the chiral pairing state in a superconducting material Sr2RuO4.
