Spin-triplet superconductivity in Sr2RuO4 due to orbital and spin fluctuations: Analyses by two-dimensional renormalization group theory and self-consistent vertex-correction method

Masahisa Tsuchiizu, Youichi Yamakawa, Seiichiro Onari +2

We study the mechanism of the triplet superconductivity (TSC) in Sr${}_2$RuO${}_4$ based on the multiorbital Hubbard model. The electronic states are studied using the recently develop…
