    • note
    • 2) the weak coupling calculation using the band structure data still gives a nonvanishing result of ∼10% of the main term, which is large enough to remove the desired tetra-critical point. Note that in the spin degenerate scenario, this dangerous term identically vanishes.

    • Norman has already investigated the relative stability of various pairing states within the same framework and failed to stabilize the following desired state. We use the newly found ferromagnetic fluctuation mode and we do not assume the strong SO coupling, thus the resulting pairing state is quite different. See M. R. Norman: Phys. Rev. B 37 (1988) 4987; ibid. 41 (1990) 170.
