Model for p- and d-wave superconductivity in heavy-fermion systems

The possibility of p- and d-wave superconductivity with the two electron constituents of the Cooper pair in a relative angular momentum l=1 or 2 and m=0 state with respect to their axis of relative motion is studied. In order for the corresponding wave function to be localized within the binding potential, the effective masses of the electrons have to be high. These considerations apply to heavy-fermion systems such as ${\mathrm{UPt}}_3$ and ${\mathrm{UBe}}_{13}$.
