Nuclear magnetic relaxation rate in the vortex state of a chiral p-wave superconductor

The site-selective nuclear spin-lattice relaxation rate T1-1 is theoretically studied inside a vortex core in a chiral p-wave superconductor within the framework of the quasiclassical theory of superconductivity. It is found that T1-1 at the vortex center depends on the sense of the chirality relative to the sense of the magnetic field. Our numerical result shows a characteristic difference in T1-1 between the two chiral states, k-barx+ik-bary and k-barx-ik-bary under the magnetic field
