Times Cited Count：2 Percentile：20.07(Physics, Multidisciplinary)We examine the effects of band structure and electron-phonon interactions on charge density waves (CDW) in terms of the extended attractive Hubbard model at half filling. It is shown that van Hove singularities well below the Fermi surface can lead to a substantial energy gain by electron-phonon coupling and result in the formation of CDW.
-wave island with a single vortexNagai, Yuki; Tanaka, Kaori*; Hayashi, Nobuhiko*
Physical Review B, 86(9), p.094526_1 - 094526_9, 2012/09
Times Cited Count：17 Percentile：57.55(Materials Science, Multidisciplinary)We demonstrate an efficient numerical method for obtaining unique solutions to the Eilenberger equation for a mesoscopic or nanoscale superconductor. In particular, we calculate the local density of states of a circular -wave island containing a single vortex. The "vortex shadow" effect is found to depend strongly on the quasiparticle energy in such small systems. We show how to construct by geometry quasiparticle trajectories confined in a finite-size system with specular reflections at the boundary, and we discuss the stability of the numerical solutions even in the case of vanishing order parameter as for nodal quasiparticles in a -wave superconductor or for quasiparticles passing through the vortex center with zero energy.
