The bound states of two electrons in the adiabatic Holstein-Hubbard model are studied numerically in one and two dimensions from the anticontinuous limit. This mode1 involves acompetition between a local electron-phonon coupling (with a classical lattice) which tends to form pairs ofelectrons and th
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)
