TRANSPORT-PROPERTIES OF THE INFINITE-DIMENSIONAL HUBBARD-MODEL

We present studies of transport properties for the infinite-dimensiona l Hubbard model. For doping of less than 30% the model shows an intere sting crossover to a moderately heavy Fermi liquid with a significantl y reduced bandwidth at low temperatures. In the crossover region we ob serve remarkable similarities in the temperature dependence of the tra nsport properties - like, e.g., linear resistivity and NMR relaxation rate - to the normal-state properties of high-T(c) superconductors.
