We study a spinless two-band model at half-filling in the limit of infinite dimensions. The ground state of this model in the noninteracting limit is a band insulator. We identify transitions to a metal and to a charge Mott insulator, using a combination of analytical, quantum Monte Carlo, and zero temperature recursion methods. The metallic phase is a non-Fermi-liquid state with algebraic local correlation functions with universal exponents over a range of parameters.

Golosov, D. I.; Ruckenstein, A. E. (SPRINGER/PLENUM PUBLISHERS, 1998-08-01)We re-examine the calculation of the transverse spin-diffusion coefficient in a dilute degenerate spin-polarized Fermi gas, for the case of s-wave scattering. The special feature of this limit is that the dependence of the ...
