Theory of resonant inelastic X-ray scattering spectrum for Ni impurities in cuprates

Tsutsui, Kenji; Toyama, Takami*; Maekawa, Sadamichi

We carry out the numerically exact diagonalization on small clusters of the d-p model with a Ni impurity site to simulate a resonant inelastic X-ray scattering spectra, as well as the single-particle excitation ones. We propose the resonant inelastic X-ray scattering experiment for Ni K edge to confirm the hole binding around the Ni impurity.
