Abstract
The electrical conductivity of the single-band Hubbard Hamiltonian is calculated by use of the Boltzmann-Transport-Equation. We lean on the antiferromagnetic approach to this Hamiltonian. We obtain a semiconductor with an energy gap due to the electronic correlations and a semiconductor to metal transition at the Néel temperature TN.Keywords
