Absence of Mott Transition in an Exact Solution of the Short-Range, One-Band Model in One Dimension
Élliott H. Lieb, Fa Yueh Wu
The short-range, one-band model for electron correlations in a narrow energy band is solved exactly in the one-dimensional case. The ground-state energy, wave function, and the chemical potentials are obtained, and it is found that the ground state exhibits no conductor-insulator transition as the correlation strength is increased.
