We show in a the mini phase diagram and Luttinger parameter Kρ, and b accordingly the ratio between triplet and singlet pairings ∣ΦT/ΦS∣ that becomes greater than 1 in the emergent TS phase. The Kρ results in the PSx and PS1 are computed within the clustered part (see Supplementary Note 3). c The charge distribution n(i) in TS (V = − 1), PSx (V = −1.7), PS1 (V = −2.4), and PS2 (V = −2.44) phases, respectively. d The charge densities n(L/2) measured at the center of the system are plotted versus V.
