Abstract

We present a theoretical study of the superconducting gap function in PrOs4Sb12 using a symmetry-based approach. A three-component order parameter in the triplet channel best describes superconductivity. The gap function is nondegenerate and the lower branch has four cusp nodes at unusual points of the Fermi surface, which lead to power law behaviors in the density of states, specific heat, and nuclear spin relaxation rate.

  34. There is an error in Table I of Ref. [32]. The triplet-paired phase with symmetry D2(E) was reported to be nodeless. However, it does, in fact, have four point nodes (approximate and rigorous) at the positions [±α,±β,0]. This result can be proved rigorously as a strict consequence of symmetry (see Appendix). This error lead to our claim (Ref. [33]) that the nodes lift away from the Fermi surface to form deep dips in the gap function at the A−B transition.
