Abstract

Generic features of the low-energy excitations in the vortex lattice state are examined by comparatively studying the self-consistent solutions of the quasiclassical Eilenberger theory both for dx2−y2-wave and s-wave pairings. This low-energy physics associated with a vortex core, nodal structure, and quasiparticle transfer between vortices governs physical properties of the vortex such as the field dependences of the zero-energy density of states, the internal field distribution, and the shrinkage of the core radius. Eminent differences between two pairings are highlighted to help analyze experimental data.
