| dc.description | We investigate the quasiparticle spectrum of a d-wave superconductor in the mixed state, focussing on the effects of varying the in-plane angular alignment (or tilting) of the vortex and crystal lattices. Our approach starts with a linearized Bogoliubov-de Gennes equation cast into a simple form by the Franz-Tešanović singular gauge transformation. The zero magnetic field spectrum is characterized by the anisotropy $α_D$ near the four Fermi-surface nodes; at large $α_D$ the model simplifies into a one-dimensional form that provides asymptotic results. Numerical and analytical results are presented and compared with previous studies. We find that tilting can be understood in terms of the one-dimensional model at large $α_D$. We see a striking dependence on the choice of singular gauge, consistent with earlier results, but do not attempt to resolve the issue of which gauge best describes the microscopic physics. | |
