Abstract

We apply a semiclassical method to the problem of field angle-dependent oscillations of the density of states and thermal conductivity for nodal superconductors and apply our results to the superconductor PrOs4Sb12. The oscillatory contributions to the thermal conductivity for all possible point node configurations for a superconductor with Th symmetry are calculated. It is found that experimental results are best accounted for by nodes in the off-axis directions [± sin ϕ0,0,± cos ϕ0], which are associated with the time-reversal breaking, triplet paired phase with symmetry D2(E).
