Supercurrent in Nodal Superconductors

Khavkine, Igor · Kee, Hae-Young · Maki, Kazumi

Original · EN

In recent years, a number of nodal superconductors have been identified; d-wave superconductors in high Tc cuprates, CeCoIn₅, and κ-(ET)₂Cu(NCS)₂, 2D f-wave superconductor in Sr₂RuO₄ and hybrid s+g-wave superconductor in YNi₂B₂C. In this work we conduct a theoretical study of nodal superconductors in the presence of supercurrent. For simplicity, we limit ourselves to d-wave and 2D f-wave superconductors. We compute the quasiparticle density of states and the temperature dependence of the depairing critical current in nodal superconductors, both of which are accessible experimentally.
