For a newly discovered iron-based high T_{c} superconductor LaFeAsO1-xFx, we have constructed a minimal model, where inclusion of all five Fe d bands is found to be necessary. The random-phase approximation is applied to the model to investigate the origin of superconductivity. We conclude that the multiple spin-fluctuation modes arising from the nesting across the disconnected Fermi surfaces realize an extended s-wave pairing, while d-wave pairing can also be another candidate.

Functional renormalization group approach to correlated fermion systems (2011, background): “As pointed out early (Kuroki et al., 2008; Mazin et al., 2008), there is approximate nesting of electron- and hole pockets which enhances particlehole susceptibilities with the wavevector connecting these pockets.”
