Electron correlations in narrow energy bands: ground state energy and metal-insulator transition

The electron correlations in narrow energy bands are examined within the framework of the Hubbard model. The single-particle Green function and energy spectrum are obtained in a paramagnetic state at half-ﬁlling by means of a new two-pole approximation. Analytical expressi...
