Quasiparticle spectrum of d-wave superconductors in the mixed state: a large Fermi-velocity anisotropy study

Luca Marinelli, B. I. Halperin

The quasiparticle spectrum of a two-dimensional d-wave superconductor in the mixed state, H_c1 << H << H_c2, is studied for large values of the ``anisotropy ratio'' alpha_D = v_F/v…
