Query: Theory of superconductivity in SrPtAs   We constructed tight-binding models for the new superconductor SrPtAs
according to first principle calculations, and by functional renormalization
group we investigated the effect of electron correlations and spin-orbital
coupling (SOC) in Cooper pairing. We found that out of the five $d$-orbitals,
the $(xz,yz)$-orbitals are the active ones responsible for superconductivity,
and ferromagnetic fluctuations enhanced by the proximity to the van Hove
singularity triggers $f$-wave triplet pairing. The superconducting transition
temperature increases as the Fermi level is closer to the van Hove singularity
until ferromagnetism sets in. The $d$-vector of the triplet pairing component
is pinned by SOC along the out-of-plane direction. Experimental perspectives
are discussed.
