Superconductivity with lines of gap nodes: density of states in the vortex
Volovik G.E.
The density of states. (DOS) produced by the vortices in the superconductors with the lines of zeros in electronic energy spectrum is calculated with application to high temperature superconductors. DOS of the isolated vortex is oc Νρξ -ÇÛÐ{ñ, λ}, where Njp is the DOS of the normal metal, £ is the coherence length, λ is the penetration length, and R is the distance between the vortices. Only a small part of the DOS results fron. the fermions, localized in the vortex core. Symmetry of the isolated vortex line in superconductors with the gap corresponding to Γ3 representation is also discussed.
