Abstract

We examine the superconducting gap nodes in crystals with tetrahedral (T_h) symmetry. The (0, 0, 1) phase of the three-dimensional order parameter in the triplet channel has nodes in the [0 0 1] directions. Following a second order phase transition to the state (0, i | η₂ |, | η₁ |), each node lifts away from the Fermi surface and splits into two deep dips. We discuss this scenario in the context of multiple superconducting phases in PrOs₄ Sb₁₂.
