Query: Exact diagonalization results for resonant inelastic x-ray scattering
  spectra of one-dimensional Mott insulators   We examine the momentum-dependent excitation spectra of indirect as well as
direct resonant inelastic x-ray scattering (RIXS) processes in half-filled
(extended) Hubbard rings. We determine the fundamental features of the
groundstate RIXS response and discuss the experimental conditions that can
allow for the low-energy part of these features to be distinguished in
one-dimensional copper-oxide materials, focusing particularly on the different
magnetic excitations occurring in indirect and direct RIXS processes. We study
the dependence of spin and charge excitations on the choice of and detuning
from resonance. Moreover, final state excitation weights are calculated as a
function of the core-hole potential strength and lifetime. We show that these
results can be used to determine material characteristics, such as the
core-hole properties, from RIXS measurements.
