| The advances made in 3^ generation light sources have recently provided new insights into the study of electron dynamics in strongly correlated systems via resonant inelastic x-ray scattering (RIXS). Improvements in resolution now offer the possibility of a direct comparison of ARPES & Raman spectra in the several eV range. In this talk I present investigations of inelastic x-ray scattering in several different contexts highlighting advances in our understanding of the dynamical charge response in correlated systems. On the basis of a spin-wave analysis and exact-diagonalization, we determine the shape of the two-magnon spectra and present calculations for resonant inelastic x-ray scattering (RIXS) in edge-shared copper oxide systems, such as CuGeO3 and Li2CuO2. The energies, orbital character and resonance profiles of excitations which can be probed via RIXS are examined. |
