    • note
    • 0 is considered a constant, like the interaction J, and may enter Φ[D] and therefore Π = δΦ/δD to arbitrary order. However, for the particular approximation shown in Fig. 7 we were not able to find the corresponding functional Φ[D].

    • note
    • Note that neither a RPA-like bubble series nor vertex corrections to the bubble need to be considered, since the fermion self-energy only consists of a Hartree diagram with spin-spin interaction.
