Enhanced photon and phonon detection in ultrastrong-coupling optomechanics — •Max Ludwig¹, Amir H.

The regime of ultrastrong coupling in optomechanics is reached when the optomechanical coupling rate becomes comparable to the cavity linewidth. In this regime we consider a setup comprising two cavity modes and a single mechanical mode. For mechanical frequencies nearly resonant to the optical level splitting the photon-phonon and the photon-photon interaction is boosted enabling QND phonon and photon detection.
