Abstract

Anomalies are found in the resistivity ρ, and NMR rate 1/T 1 of the infinite dimensional Hubbard model using quantum Monte Carlo and the non-crossing approximation. For temperatures greater than the Kondo scale T 0, 1/T 1 ~ a +bT ρ ~ c + dT (a, b, c, d constants). Similar behaviour has been seen above T c in the cuprate high temperature superconductors. For T ≲ T0 both ρ and 1/T 1 cross over to Fermi- liquid-like behaviour. In addition, ρ, 1/T 1, the susceptibility and the specific heat show scaling with T/T 0.
