We analyze the optical conductivity of the two-dimensional Hubbard model using the projection technique. The current self-energy and the static current susceptibility are evaluated perturbatively applying a novel real space summation technique. Results for the Drude weight and the incoherent spectru
Pairing mediated by charge-transfer and magnetic fluctuations is examined for a two-component (d and p) Hubbard model in 2D with hopping (tnd),Short-range on-site (Ud,UD) and nearest-neighbor (Vc) repulsive interactions within (a) the randBm-phase approximation and (b) a strong coupling (tnd<E U d)
