Singularity of the vortex density of states in d-wave superconductors

Abstract
In d-wave superconductors, the electronic density of states (DOS) induced by a vortex exhibits a divergence at low energies: Nvortex(E) ∼1/|E|. This divergence is the result of gap nodes in the spectrum of excitation outside the vortex core. The heat capacity in two regimes, T2/Tc2B/Bc2 and T2/Tc2B/Bc2, is discussed.
