Here we show the data of U = 1.6. a Singlet and triplet pairing correlations at a fixed (long) distance r = 20. The yellow strip represents the transition point Vc ≃ −1 from spin density wave (SDW) to triplet superconducting (TS) phase. b The calculated ratios ∣ΦT/ΦS∣, plotted in a log-log scale, exhibit excellent agreement with the scaling \({r}^{{K}_{\rho }-1}\) (blue solid lines).
