Slave boson theory of the extended Falicov-Kimball model
P. M. R. Brydon
The extended Falicov-Kimball model, with both an on-site hybridization potential and dispersive narrow band, is examined within the saddle-point approximation to the Kotliar-Rucken…
Charge Order in the Falicov-Kimball Model
P. M. R. Brydon, M. Gulacsi
We examine the spinless one-dimensional Falicov-Kimball model (FKM) below half-filling, addressing both the binary alloy and valence transition interpretations of the model. Using…
Fractionally Charged Polarons and Phase Separation in an Extended Falicov-Kimball Model
P. M. R. Brydon, J. -X. Zhu, A. R. Bishop
We present the first numerical study of the Falicov-Kimball model extended by an on-site hybridization away from the particle-hole symmetry point. Stable polaronic distortions of t…
Bosonization solution of the Falicov-Kimball model
P. M. R. Brydon, M. Gulacsi
We use a novel approach to analyze the one dimensional spinless Falicov-Kimball model. We derive a simple effective model for the occupation of the localized orbitals which clearly…
Competing Orderings in an Extended Falicov-Kimball Model
P. M. R. Brydon, Jian-Xin Zhu, M. Gulacsi +1
We present a Hartree-Fock study of the Falicov-Kimball model extended by both on-site and non-local hybridization. We examine the interplay between excitonic effects and the charge…
Electronic polarons in an extended Falicov-Kimball model
P. M. R. Brydon, M. Gulacsi, A. R. Bishop
We examine the one-dimensional spinless Falicov-Kimball model extended by a hybridization potential between the localized and itinerant electron states. Below half-filling we find…
