Abstract: The coupling of optical and mechanical degrees of freedom is the underlying principle of many techniques to measure mechanical displacement, from macroscale gravitational wave detectors to microscale cantilevers used in scanning probe microscopy. Recent experiments have reached a regime where the back-action of photons caused by radiation pressure can influence the optomechanical dynamics, giving rise to a host of long-anticipated phenomena. Here we review these developments and discuss the opportunities for innovative technology as well as for fundamental science.

TL;DR: In this paper, it was shown that coupled optical microcavities bear all the hallmarks of parity-time symmetry; that is, the system dynamics are unchanged by both time-reversal and mirror transformations.

TL;DR: 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.
On the measurement of a weak classical force coupled to a quantum mechanical oscillator. i. issues of principle
TL;DR: In this paper, the authors considered a new type of quantum nondemolition measurement called back-action-evading measurement, where the real part of the harmonic oscillator's complex amplitude is measured by a single transducer.
Quantum Theory of Cavity-Assisted Sideband Cooling of Mechanical Motion
TL;DR: It is found that reaching the quantum limit of arbitrarily small phonon numbers requires going into the good-cavity (resolved phonon sideband) regime where the cavity linewidth is much smaller than the mechanical frequency and the corresponding cavity detuning.

TL;DR: In this article, the authors reported the detection of an individual electron spin by magnetic resonance force microscopy (MRFM) and achieved a spatial resolution of 25nm in one dimension for an unpaired spin in silicon dioxide.
Radiation-pressure cooling and optomechanical instability of a micromirror
TL;DR: An experiment where a micromechanical resonator is used as a mirror in a very high-finesse optical cavity, and its displacements are monitored with unprecedented sensitivity, and a radiation-pressure-induced instability of the resonators is observed.
