The Hubbard model within the equations of motion approach
F. Mancini, A. Avella
The Hubbard model has a special role in Condensed Matter Theory as it is considered as the simplest Hamiltonian model one can write in order to describe anomalous physical properti…
New perspectives on the Ising model
Ferdinando Mancini
The Ising model, in presence of an external magnetic field, is isomorphic to a model of localized interacting particles satisfying the Fermi statistics. By using this isomorphism,…
A generating functional approach to the Hubbard model
Yu. A. Izyumov, N. I. Chaschin, D. S. Alexeev +1
The method of generating functional is generalized to the case of strongly correlated systems, and applied to the Hubbard model. For the electronic Green's function constructed for…
Fermionic systems with charge correlations
Ferdinando Mancini
In this paper, we show that a system of localized particles, satisfying the Fermi statistics and subject to finite-range interactions, can be exactly solved in any dimension. In fa…
