Cu K -edge resonant inelastic x-ray scattering in edge-sharing cuprates
Résumé
We present calculations for resonant inelastic x-ray scattering ͑RIXS͒ in edge-shared copper oxide systems, such as Li 2 CuO 2 and CuGeO 3 , appropriate for hard x-ray scattering, such as the copper K edge. We perform exact diagonalizations of the multiband Hubbard model and determine the energies, orbital character, and resonance profiles of excitations which can be probed via RIXS. We find excellent agreement with recent results on Li 2 CuO 2 and CuGeO 3 in the 2-7 eV photon energy loss range.
