Description
Excitation spectra of resonant inelastic x-ray scattering (RIXS) processes in one-dimensional Mott insulators are presented and discussed. The RIXS cross section of Hubbard and extended Hubbard models on finite half-filled chains is evaluated using exact diagonalization. The fundamental features of the obtained spectra reveal the different magnetic excitations occuring in indirect and direct RIXS processes, corresponding to copper K- and L-edge resonances in experiments on quasi-1D cuprates. The spectral features for each process are studied in a broad range of parameter sets and it is shown that by comparison to experiment, physical properties, such as the effect of the intermediate state core hole, can be quantitatively estimated.
