Anomalous properties of the Hubbard model in infinite dimensions

Abstract
Anomalies are found in the resistivity ρ and NMR rate 1/T1 of the infinite-dimensional Hubbard model using quantum Monte Carlo calculations and the noncrossing approximation. For temperatures greater than the ‘‘Kondo scale’’ T0, we obtain 1/T1a+bT and ρ∼c+dT (a, b, c, d constants). For temperatures TT0 we infer from a saturation of the effective mass of the carriers that the ground state of the system is a Fermi liquid.
