In contrast to multigap superconductors (e.g. MgB2), the low-temperature properties of nodal superconductors are dominated by nodal excitations. Here we extend for a variety of nodal superconductors the earlier work by Simon and Lee and Kübert and Hirschfeld. The scaling relations seen in the thermodynamics and the thermal conductivity will provide an unequivocal test of nodal superconductivity.
