    Optical conductivity of the one-dimensional dimerized Hubbard model at quarter filling

    We investigate the optical conductivity in the Mott insulating phase of the one-dimensional extended Hubbard model with alternating hop** terms (dimerization) at quarter band filling. Optical spectra are ca...

    Fourth-order perturbation theory for the half-filled Hubbard model in infinite dimensions

    We calculate the zero-temperature self-energy to fourth-order perturbation theory in the Hubbard interaction U for the half-filled Hubbard model in infinite dimensions. For the Bethe lattice with bare bandwidth W
