Query: Resonant Inelastic X-Ray Scattering as a Probe of the Phase and
  Excitations of the Order Parameter of Superconductors   The capability to probe the dispersion of elementary spin, charge, orbital,
and lattice excitations has positioned resonant inelastic x-ray scattering
(RIXS) at the forefront of photon science. Here we develop the scattering
theory for RIXS on superconductors, calculating its momentum-dependent
scattering amplitude. Considering superconductors with different pairing
symmetries, we show that the low-energy scattering is strongly affected by the
superconducting gap and coherence factors. This establishes RIXS as a tool to
disentangle pairing symmetries and to probe the elementary excitations of
unconventional superconductors.
