多组分 Falicov-Kimball 模型在无限维下的精确解

presented for the infinite-dimensional multi-component Falicov-Kimball model for arbitrary concentration of d- and f-electrons. The emphasis is on a descriptive derivation of important physical quantities by the equation of motion technique. We provide a thorough discussion of the f-electron Green function and of the susceptibility to spontaneous hybridization. The solutions are used to illustrate different physical systems ranging from the high-temperature phase of the YbInCu4 family of materials to an examination of classical intermediate valence systems that can develop a spontaneous hybridization at T=0.
