Transport properties of strongly correlated metals: A dynamical mean-field approach
Physical Review B (Condensed Matter)
The temperature dependence of the transport properties of the metallic phase of a frustrated Hubbard model on the hypercubic lattice at half-filling are calculated. Dynamical mean-field theory, which maps the Hubbard model onto a single impurity Anderson model that is solved self-consistently, and becomes exact in the limit of large dimensionality, is used. As the temperature increases there is a smooth crossover from coherent Fermi liquid excitations at low temperatures to incoherentdoi:10.1103/physrevb.61.7996 fatcat:zha377jvv5dm5jtqnxv46vsyka
