Electron Correlations in Narrow Energy Bands: Ground State Energy and Metal-Insulator Transition

Leonid Didukh, Yuriy Skorenkyy

The electron correlations in narrow energy bands are examined in framework of the Hubbard model. The single-particle Green function and energy spectrum are obtained in paramagnetic…

A New Two-Pole Approximation in the Hubbard Model. Metal-Insulator Transition

Leonid Didukh

A new two-pole approximation, which allows to describe the transition from an insulating state to a metallic one at increase of bandwidth, and also the observable in some compounds…
