C, p. 336-337, 1994.0921-4526http://hdl.handle.net/11449/132377A 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- and/or spin-ordered phases. We calculate the necessary correlation functions to build the EHM phase diagram.336-337engCorrelation methodsCrystal latticesMathematical modelsMathematical operatorsMatrix algebraPhase diagramsExtended Hubbard modelGreens functionTight binding HamiltonianOrder disorder transitionsArtigo10.1016/0921-4526(94)91828-7Acesso restrito2-s2.0-0028760648
