Emery vs. Hubbard model for cuprate superconductors: a Composite Operator Method study
Adolfo Avella, Ferdinando Mancini, Francesco Paolo Mancini +1
Within the Composite Operator Method (COM), we report the solution of the Emery model (also known as p-d or three band model), which is relevant for the cuprate high-Tc superconduc…
Correlation-induced band suppression in the two-orbital Hubbard model
E Plekhanov, A Avella, F Mancini +1
The orbital degrees of freedom are of vital importance in explanation of various phenomena. Among them is the orbital-selective Mott transition (OSMT), which is thought to occur in…
Different orderings in the narrow-band limit of the extended Hubbard model on the Bethe lattice
F. Mancini, F. P. Mancini
We present the exact solution of a system of Fermi particles living on the sites of a Bethe lattice with coordination number z and interacting through on-site U and nearest-neighbo…
Extended Hubbard model in the presence of a magnetic field
F. Mancini, F. P. Mancini
Within the Green's function and equations of motion formalism it is possible to exactly solve a large class of models useful for the study of strongly correlated systems. Here, we…
Role of the attractive intersite interaction in the extended Hubbard model
F. Mancini, F. P. Mancini, A. Naddeo
We consider the extended Hubbard model in the atomic limit on a Bethe lattice with coordination number z. By using the equations of motion formalism, the model is exactly solved fo…
Magnetic and thermal properties of a one-dimensional spin-1 model
F. Mancini, F. P. Mancini
We study the one-dimensional S=1 Blume-Emery-Griffiths model. Upon transforming the spin model into an equivalent fermionic model, we provide the exact solution within the Green's…
