Influence of Fermi surface topology on the quasiparticle spectrum in the vortex state
S. Graser, T. Dahm, N. Schopohl
We study the influence of Fermi surface topology on the quasiparticle density of states in the vortex state of type II superconductors. We observe that the field dependence and the…

Fermi surface topology and vortex state in MgB2
T. Dahm, S. Graser, N. Schopohl
Based on a detailed modeling of the Fermi surface topology of MgB2 we calculated the anisotropy of the upper critical field Bc2 within the two gap model. The sigma-band is modeled…
