Mixed-state quasiparticle spectrum for {ital d}-wave superconductors
- Department of Physics, Indiana University, Bloomington, Indiana 47405 (United States)
Controversy concerning the pairing symmetry of high-{ital T}{sub {ital c}} materials has motivated an interest in those measurable properties of superconductors for which qualitative differences exist between the {ital s}-wave and {ital d}-wave cases. We report on a comparison between the microscopic electronic properties of {ital d}-wave and {ital s}-wave superconductors in the mixed state. Our study is based on self-consistent numerical solutions of the mean-field Bogoliubov--de Gennes equations for phenomenological BCS models which have {ital s}-wave and {ital d}-wave condensates in the absence of a magnetic field. We discuss differences between the {ital s}-wave and the {ital d}-wave local density of states, both near and away from vortex cores. Experimental implications for both scanning-tunneling-microscopy measurements and specific-heat measurements are discussed.
