Anisotropic thermodynamics and scaling of d-wave superconductors in the vortex state

I. Vekhter, P. J. Hirschfeld, J. P. Carbotte +1

The density of states of a 2D d-wave superconductor in the vortex state with applied magnetic field in the plane is shown to exhibit fourfold oscillations as a function of…

Quasiparticle Transport in the Vortex State of Unconventional Superconductors

P. J. Hirschfeld

I consider the problem of the vortex contribution to quasiparticle transport in unconventional superconductors with line nodes, a nd argue that the magnetic field dependence of tra…

Magnetic field -induced phase transition in a -wave superconductor at low temperatures

P. J. Hirschfeld, P. Wölfle

We consider, within BCS weak coupling theory, the instability of a -wave superconductor to a state of mixed symmetry , . In zero magnetic field we sh…

Effects of Fermi Surface Anisotropy on Unconventional Superconductivity in UPt_3

G. Haran, P. J. Hirschfeld, M. Sigrist

We discuss the weak-coupling BCS theory of the heavy fermion superconductor UPt_3, accounting for that system's anisotropic, multisheeted Fermi surface by expanding the order param…
