The Falicov-Kimball model : a review of exact results and extensions
The Falicov-Kimball model is a simplified version of the the Hubbard model in which only one type of electron (e.g. spin down) is allowed to hop. It describes in particular a system of spinless quantum particles interacting with classical particles (Ising spins). In this review we present the progress which has been accomplished in the last decade concerning this model, with an emphasis on rigo...
متن کاملGround States and Flux Conngurations of the Two{dimensional Falicov{kimball Model
The Falicov{Kimball model is a lattice model of itinerant spinless fermions (\electrons") interacting by an on{site potential with classical particles (\ions"). We continue the investigations of the crystalline ground states that appear for various lling of electrons and ions, for large coupling. We investigate the model for square as well as triangular lattices. New ground states are found and...
متن کاملPhase separation due to quantum mechanical correlations.
Can phase separation be induced by strong electron correlations? We present a theorem that affirmatively answers this question in the Falicov-Kimball model away from half filling, for any dimension. In the ground state the itinerant electrons are spatially separated from the classical particles.

In this letter we study the ground-state phase diagram of the one-dimensional Falicov-Kimball model. This model was proposed to describe metal-insulator transitions [ 1] and has since been investigated in connection with a variety of problems such as binary alloys [ 2], ordering in mixed-valence systems [ 3], and the formation of ionic crystals [ 4]. It is the latter language we shall use here,...
متن کاملFalicov - Kimball Model
The “Falicov-Kimball model” was first considered by Hubbard and Gutzwiller in 1963– 65 as a simplification of the Hubbard model. Falicov and Kimball introduced in 1969 a model that included a few extra complications, in order to investigate metal-insulator phase transitions in rare-earth materials and transition-metal compounds. Experimental data suggested that this transition is due to the int...
