Hubbard model for a cubic cluster

Physical Review B, 1987
The ground-state and thermodynamic properties of a simple Hubbard Hamiltonian are studied for an eight-site cubic cluster as functions of the number of electrons and the strength of the electron interaction. The ground-state energy and spin are determined, and the excitation spectrum is computed.

Phase separation in the Hubbard model

Physical Review B, 1993
We use the correlated-random-field approximation and a conditional coherent-potential approximation to study the ground-state phase diagram of the one-band Hubbard model. Our approach incorporates both spin and electron correlations. It has been found that for certain values of the parameters of the model, in addition to paramagnetic, ferromagnetic ...

Constraints on pairings in the Hubbard model

Physical Review B, 1995
Pairing operators of electrons with an arbitrary distance on a square lattice are defined in each possible wave channel, {ital s}, {ital p}, {ital d}{sub {ital x}}{sup 2}{minus}{ital y}{sup 2}, {ital d}{sub {ital x}{ital y}}, and {ital g}{sub {ital x}}{sup 3}{ital y}{minus}{ital xy}{sup 3}. Exact identities among pairing amplitudes in the Hubbard model
