Local Quasiparticle Density of States in unconventional Type-II Superconductors — •Christian Iniotakis and Nils Schopohl — Institut für Theoretische Physik, Universität Tübingen, Auf der Morgenstelle 14, D-72076 Tübingen
Our aim is to calculate the quasiclassical propagator in unconventional (d-wave) superconductors in the vortex state. We assume a clean and homogeneous superconductor. Near the phase transition at Hc2 the spacial variation of the gap function is given by the well-known Abrikosov solution. Concentrating on the quadratic and hexagonal vortex lattice we present calculations of the local quasiparticle density of states. Our results have been achieved by using the Riccati-parametrization of the quasiclassical Eilenberger theory. Additionally, basic symmetry relations of the vortex lattice have been taken into account.
