Ordered phases in the extended Hubbard model
(Elsevier B.V., 1994-04-02)
A novel method to probe the diverse phases for the extended Hubbard model (EHM), including the correlated hopping term, is presented. We extend an effective medium approach [1] to a bipartite lattice, allowing for charge- ...

Extended Hubbard model: Charge ordering and Wigner-Mott transition
(American Physical Society, 2010-10)
Strong correlations effects, which are often associated to the approach to a Mott insulating state, in some cases may be observed even far from half filling. This typically happens whenever the intersite Coulomb repulsion ...
Susceptibilidade magnética de um modelo de Hubbard estendido com interação ao atrativa
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2012-01-17)
Anomalous properties of the normal state of a strongly correlated electron system described
by an attractive extended Hubbard model are investigated. The equations of motion
of the Green s functions are calculated with the ...
Two-particle correlations in the-dimensional hubbart model: a ground-state analytical solution
(Revista Mexicana de Física, 2009)
Mean-field phase diagram of the extended Bose-Hubbard model of many-body cavity quantum electrodynamics
(American Physical Society, 2019-04-30)
We investigate the mean-field phase diagram of the Bose-Hubbard model with infinite-range interactions in two dimensions. This model describes ultracold bosonic atoms confined by a twodimensional optical lattice and ...
