Phase separation and the segregation principle in the infinite-U spinless Falicov-Kimball model
نویسنده
چکیده
The simplest statistical-mechanical model of crystalline formation ~or alloy formation! that includes electronic degrees of freedom is solved exactly in the limit of large spatial dimensions and infinite interaction strength. The solutions contain both second-order phase transitions and first-order phase transitions ~that involve phase separation or segregation! which are likely to illustrate the precursor physics behind the static charge-stripe ordering in cuprate systems. In addition, we find that the spinodal-decomposition temperature satisfies an approximate scaling law. @S0163-1829~99!05527-7#

Segregation and charge-density-wave order in the spinless Falicov-Kimball model
The spinless Falicov-Kimball model is solved exactly in the limit of infinite dimensions on both the hypercubic and Bethe lattices. The competition between segregation, which is present for large U, and chargedensity-wave order, which is prevalent at moderate U, is examined in detail. We find a rich phase diagram that displays both of these phases. The model also shows nonanalytic behavior in t...

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 کاملWeak-coupling Treatment of Electronic (Anti-)Ferroelectricity in the Extended Falicov-Kimball Model
We study the (spinless) Falicov-Kimball model extended by a finite band width (hopping tf ) of the localized (f-) electrons in infinite dimensions in the weak-coupling limit of a small local interband Coulomb correlation U for half filling. In the case of overlapping conductionand f-bands different kinds of ordered solutions are possible, namely charge-density wave (CDW) order, electronic ferro...
متن کاملNonequilibrium perturbation theory of the spinless Falicov-Kimball model: Second-order truncated expansion in U
We perform a perturbative analysis for the nonequilibrium Green’s functions of the spinless Falicov-Kimball model in the presence of an arbitrary external time-dependent but spatially uniform electric field. The conduction-electron self-energy is found from a strictly truncated second-order perturbative expansion in the local electron-electron repulsion U. We examine the current at half-filling...
متن کاملSpinless Falicov-Kimball model (annealed binary alloy) from large to small dimensions.
The phase diagram for the spinless Falicov-Kimball model on a hypercu-bic lattice is reexamined in the limits of large and small dimensions (for the half-lled ion case). This model is identical to the thermodynamical problem of an annealed binary alloy with diagonal disorder. The phase diagram for the innnite-dimensional case is remarkably similar to the conjectured phase diagram for the one-di...
