We examine the doping dependence of the resonant inelastic X-ray scattering (RIXS) by using numerically exact diagonalization technique on finite size cluster systems. The single-band Hubbard model with long-range hoppings is adopted to describe the Zhang-Rice singlet band (ZRB) and upper Hubbard ba

We discuss the nature of the resonant enhancement factor which enters the K-edge RIXS cross-section within the framework of a three-band Hubbard model of the cuprates. The enhancement factor is shown to display peaks as a function of the incident photon energy related to the Van Hove singularities (
We report the energy and polarization dependence of resonant inelastic X-ray scattering from Nd 2 CuO 4 . An energy loss feature at Ο³6 eV is observed in the vicinity of the Cu K-edge. Numerical calculations based on the Anderson impurity model identify this as a charge transfer excitation to the ant
