The anomalous temperature dependences of conductivity and the Hall constant are calculated. It is shown that these anomalies are defined by the electron-electron scattering, because the energy-conserving surface intersects the Van Hove singularities.
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)
Quantum Monte Carlo results for both the repulsive and attractive Hubbard model on a square lattice are discussed. Results on pairing correlation in the repulsive Hubbard model are summarized. Momentum distribution function in the attractive Hubbard model is presented and compared with mean field re
