Mean-field phase diagram in the vicinity of f = −1/2 and at finite temperature. TSC topological superconductor, IVCW inter-valley coherence wave. The TSC appears below Tc around the IVCW insulator on both the hole and electron doped sides, with a d + id and p−ip mixed inter-valley pairing. The IVCW order on sets at the temperature TIVCW and becomes strong enough to full gap out the Fermi surface below Tins. On the hole doping side, the metallic IVCW phase has a single hole pocket with twofold spin degeneracy. The transition temperatures Tc and TIVCW are correlated since they arise from the same interaction gRPA
