<i>p</i>-wave superconductivity in heavy-fermion systems: An induced-interaction approach

Abstract

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, ${F}_{0}^{a}$\ensuremath{\rightarrow}-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.
