The spectral function A c ( ω ) of the conduction electrons and A f ( ω ) of local electron as a function of momentum on the path Γ – K – M – Γ in the Brillouin zone at temperature T = 1/20. The antiferromagnetic-order phase for hybridization V = 1.0 corresponds to the cases of panels (a1) and (a2). The Kondo singlet phase for hybridization V = 4.0 corresponds to the cases of panels (b1) and (b2).
