    • In ref. 18, they proposed the following two procedures: One is the modification of the self-energy Σ0 obtained by the second-order perturbation in the form Σ, U〈n -σ〉, AΣ0/1- BΣ0. The other is introduction of the quantity μ0, which shifts the hybridization function Δ(ω) and enters the Weiss field G0(ω) in the form G 0(ω, 1/ω+μ0-Δ(ω, This quantity μ0 is adjusted by requiring the Luttinger sum rule ∫-i∞i∞ dω/(2πi)G(ω) ∂Σ/∂ω. See ref. 18 for details. Our idea of adjusting the Weiss field with quantity μ has similarity to their latter procedure
