Theory of chiral $p$-wave superconductivity with near-nodes for Sr${}_2$RuO${}_4$

Abstract

We use functional renormalization group method to study a three-orbital model for superconducting Sr${}_2$RuO${}_4$. Although the pairing symmetry is found to be chiral $p$-wave, the atomic spin-orbit coupling induces near-nodes for quasiparticle excitations. Our theory explains a major experimental puzzle between $d$-wave-like feature observed in thermal experiments and the chiral $p$-wave triplet pairing revealed in nuclear-magnetic-resonance and Kerr effect.
