Query: Optomechanical amplification driven by interference of phonon-exciton
  and phonon-photon couplings   We study theoretically optomechanical damping and amplification spectra for
vibrations interacting with excitonic polaritons in a zero-dimensional
microcavity. We demonstrate, that the spectra strongly depend on the ratio of
the exciton-phonon and the photon-phonon coupling constants. The interference
between these couplings enables a situation when optomechanical gain exists
either only for a lower polaritonic resonance or only for an upper polaritonic
resonance. Our results provide insight in the optomechanical interactions in
various multi-mode systems, where several resonant oscillators, such as
photons, plasmons, or excitons are coupled to the same vibration mode.
