摘要

The metal-insulator transition in a generalized Hubbard model with bondcharge interaction has been studied by means of the auxiliary field technique. The system exhibits both the conventional Mott-Hubbard transition, characterized by a continuous change in the number of current carriers, and a novel first-order metal-insulator transition owing to the bond-charge interaction, at which there is a discontinuity in the number of current carriers. The phase diagram in the parameter space spanned by the effective kinetic energy and the effective bond-charge interaction is presented for the three-dimensional case.
