摘要：

A spinless two-band model is studied in infinite-dimension limit. Starting from the atomic limit, the formal exact solution of the model is obtained by means of a perturbative treatment of the hopping and hybridization terms. The model is solved in closed form in high dimensions assuming no local spin fluctuations. The non-Fermi-liquid properties appearing in the metallic phase are analyzed through the behavior of the density of states and the self-energy near the Fermi level.
