Abstract
In order to identify the pairing symmetry with chirality, we study site-selective NMR in chiral p-wave superconductors. We calculate local nuclear relaxation rate T1-1 in the vortex lattice state by Eilenberger theory, including the applied magnetic field dependence. We find that T1-1 in the NMR resonance line shape is different between two chiral states p±(=px±ipy), depending on whether the chirality is parallel or antiparallel to the vorticity. Anomalous suppression of T1-1 occurs around the vortex core in the chiral p- wave due to the negative coherence term coming from the odd-frequency s-wave Cooper pair induced around the vortex with Majorana state.
