Field dependence of the vortex structure in chiral p-wave superconductors -: art. no. 224517

To investigate the different vortex structures between two chiral pairings p(x)+/-ip(y), we calculate the pair potential, the internal field, the local density of states, and the free energy in a vortex lattice state based on the quasiclassical Eilenberger theory, and analyze the magnetic-field dependence. The induced opposite chiral component of the pair potential plays an important role in the vortex structure. It also produces an rootH behavior of the zero-energy density of states at higher field. These results are helpful when we understand the vortex states in Sr2RuO4.
