The quantum nonlinear regime of optomechanics is reached when nonlinear effects of the radiation pressure interaction are observed at the single-photon level. This requires couplings larger than the mechanical frequency and cavity-damping rate, and is difficult to achieve experimentally. Here we show how to exponentially enhance the single-photon optomechanical coupling strength using only additional linear resources. Our method is based on using a large-amplitude, strongly detuned mechanical…

TLDR
This work exploits subwavelength optical field confinement to realize record-high interaction strengths, such that thermal motion induces optical frequency fluctuations larger than the intrinsic optical linewidth, and operates in a new — fully nonlinear — regime.
Quantum simulation of tunable and ultrastrong mixed-optomechanics.

It is shown that the mixed-optomechanical interactions can enter the single-photon strong-coupling and even ultrastrong-Coupling regimes and the thermal noise of the driven mode can be suppressed totally by introducing a proper squeezed vacuum bath.

We propose a reliable scheme to realize a generalized ultrastrong optomechanical coupling in a two-mode cross-Kerr-type coupled system, where one of the bosonic modes is strongly driven. The
Reaching the optomechanical strong-coupling regime with a single atom in a cavity
A major goal within the field of optomechanics is to achieve the single-photon strong coupling regime, wherein even a mechanical displacement as small as the zero-point uncertainty is enough to shift

The realization of multimode optomechanical interactions in the single-photon strong-coupling regime is a desired task in cavity optomechanics, but it remains a challenge in realistic physical
Photon blockade by enhancing coupling via a nonlinear medium.
TLDR

The regime of single-photon strong coupling is reached when the optical shift induced by a single phonon becomes comparable to the cavity linewidth, and a setup in this regime comprising two optical modes and one mechanical mode is considered.

Optomechanically induced transparency in the nonlinear quantum regime.
TLDR
It is demonstrated that pulsed transistorlike switching of transmission still works even in this regime, and it is shown that optomechanically induced transparency at the second mechanical sideband could be a sensitive tool to see first indications of the nonlinear quantum nature of the Optomechanical interaction even for single-photon coupling strengths significantly smaller than the cavity linewidth.
Non-classical light generated by quantum-noise-driven cavity optomechanics
TLDR
This work reports an implementation of cavity optomechanics using ultracold atoms in which the collective atomic motion is dominantly driven by quantum fluctuations in radiation pressure, and the back-action of this motion onto the cavity light field produces ponderomotive squeezing.

TLDR
A cavity which is detuned by the motion of a 50-nm-thick dielectric membrane placed between two macroscopic, rigid, high-finesse mirrors is demonstrated, which segregates optical and mechanical functionality to physically distinct structures and avoids compromising either.
Single-photon optomechanics.
TLDR
This study shows that in this limit the power spectrum has multiple sidebands and that the cavity response has several resonances in the resolved-sideband limit, and finds non-Gaussian steady states of the mechanical oscillator when multiphoton transitions are resonant.
