p-wave superconductivity in heavy-fermion systems: An induced-interaction approach

The Fermi-liquid parameters for heavy-fermion systems are calculated. The spin fluctuations ($F_0^a$) renormalize the effective mass modestly, but significantly affect the triplet scattering amplitude; consequently, p-wave pairing occurs. Additionally in the extreme limit of this model, $F_0^a$→-0.906 while the effective mass diverges algebraically, suggesting a Mott-like localization. This is a consequence of the finite range of the effective interactions and many-body correlations.
