Abstract:
We study resonant inelastic x-ray scattering (RIXS) peaks corresponding to low-energy particle-hole excited states of metallic FeTe and semimetallic TiSe2 for photon incident energy tuned near the L-3 absorption edge of Fe and Ti, respectively. We show that the cross-section amplitudes are well described within a renormalization-group theory where the effect of the core electrons is captured by effective dielectric functions expressed in terms of the the atomic scattering parameters f(1) of Fe and Ti. This method can be used to extract the dynamical structure factor from experimental RIXS spectra in metallic systems.
