Query: Atom recoil in collectively interacting dipoles using quantized
  vibrational states   The recoil of atoms in dense ensembles during light matter interactions is
studied using quantized vibrational states for the atomic motion. The recoil
resulting from the forces due to the near-field collective dipole interactions
and far-field laser and decay interactions are explored. The contributions to
the recoil and the dependence on the trap frequency of the different terms of
the Hamiltonian and Lindbladian are studied. These calculations are compared
with previous results using the impulse model in the slow oscillation
approximation. Calculations in highly subradiant systems show enhanced recoil
indicating that recoil effects cannot be ignored in such cases.
