Exact solution of the extended Hubbard model in the atomic limit on the Bethe Lattice
F. Mancini, F. P. Mancini, A. Naddeo
We study the phase diagram at finite temperature of a system of Fermi particles on the sites of the Bethe lattice with coordination number z and interacting through onsite U and ne…
Fermionic systems with charge correlations on the Bethe lattice
Ferdinando Mancini, Adele Naddeo
A fermionic model, built up of q species of localized Fermi particles, interacting by charge correlations, is isomorphic to a spin-q/2 Ising model. However, the equivalence is only…
Inhomogeneous charge ordering of a spinless fermionic system on the Bethe lattice
Ferdinando Mancini, Francesco Paolo Mancini, Adele Naddeo
We show that a system of spinless Fermi particles, localized on the sites of the Bethe lattice with coordination number z and interacting through a repulsive nearest-neighbor inter…
Green's Function Formalism for Highly Correlated Systems
Ferdinando Mancini, Adolfo Avella
We present the Composite Operator Method (COM) as a modern approach to the study of strongly correlated electronic systems, based on the equation of motion and Green's function met…
A class of solvable models in Condensed Matter Physics
Ferdinando Mancini
In this paper, we show that there is a large class of fermionic systems for which it is possible to find, for any dimension, a finite closed set of eigenoperators and eigenvalues o…
Ergodicity in Strongly Correlated Systems
Adolfo Avella, Ferdinando Mancini, Evgeny Plekhanov
We present a concise, but systematic, review of the ergodicity issue in strongly correlated systems. After giving a brief historical overview, we analyze the issue within the Green…
