      abstract     = {Studying the antiferromagnetic phase of the Hubbard model
                      by dynamical mean-field theory, we observe striking
                      differences with static (Hartree-Fock) mean field: The
                      Slater band is strongly renormalized and spectral weight is
                      transferred to spin-polaron sidebands. Already for
                      intermediate values of the interaction U the overall
                      bandwidth is larger than in the Hartree-Fock mean field and
                      the gap is considerably smaller. Such differences survive
                      any renormalization of U. Our photoemission experiments for
                      Cr-doped V2O3 show spectra qualitatively well described by
                      dynamical mean-field theory.},
