a Interorbital spin-triplet Cooper pair and b Josephson junction. Fermi lines in the normal state for different electronic parameters: c four Fermi lines at (λSO/t, αOR/t, μ/t) = (0.10, 0.20, 0.00) and d six Fermi lines configuration at (λSO/t, αOR/t, μ/t) = (0.10, 0.20, 0.35). Spin-triplet d-vectors along the different Fermi lines are reported in the panels e–j for the various bands with orange and cyan indicating the Fermi contours corresponding to the configurations in c and d, respectively. The texture of the d-vector is significantly dependent on the band/orbital character and on the position in the momentum space.
