Title: Reentrant insulator-metal transition in the half-filled Hubbard model

Abstract

Using the {ital d}={infinity} or local-approximation approach to the half-filled Hubbard model on a compressible lattice, we present a detailed study of the transport and structural properties near the paramagnetic metal-insulator transition. The results describe qualitatively most of the observed data in V{sub 2}O{sub 3}, including the metal-insulator-metal crossover [Kuwamoto {ital et} {ital al}., Phys. Rev. B {bold 22}, 2626 (1980)]. In addition, we discuss an interesting and intrinsic reentrance feature in the resistivity of the half-filled Hubbard model at high temperatures.
