Query: Inelastic light scattering from a Mott insulator   We propose to use Bragg spectroscopy to measure the excitation spectrum of
the Mott insulator state of an atomic Bose gas in an optical lattice. We
calculate the structure factor of the Mott insulator taking into account both
the selfenergy corrections of the atoms and the corresponding dressing of the
atom-photon interaction. We determine the scattering rate of photons in the
stimulated Raman transition and show that by measuring this scattering rate in
an experiment, in particular the excitation gap of the Mott insulator can be
determined.
