Multimode circuit optomechanics near the quantum limit
The coupling of distinct systems underlies nearly all physical phenomena. A basic instance is that of interacting harmonic oscillators, giving rise to, for example, the phonon eigenmodes in a lattice. Of particular importance are the interactions in hybrid quantum systems, which can combine the benefits of each part in quantum technologies. Here we investigate a hybrid optomechanical system hav...
متن کاملClassical Analysis of Cavity Optomechanics
We present a classical analysis of a mechanical oscillator subject to the radiation pressure force due to light circulating inside a driven optical cavity. Our analysis is related to the problem of cooling an optomechanical setup to degrees near the ground state of mechanical motion according to quantum theory. Achieving this could provide an insight into quantum phenomena occurring in macro-sc...
متن کاملCavity Optomechanics at Millikelvin Temperatures
The field of cavity optomechanics, which concerns the coupling of a mechanical object’s motion to the electromagnetic field of a high finesse cavity, allows for exquisitely sensitive measurements of mechanical motion, from large-scale gravitational wave detection to microscale accelerometers. Moreover, it provides a potential means to control and engineer the state of a macroscopic mechanical o...
متن کاملParametric normal-mode splitting in cavity optomechanics.
Recent experimental progress in cavity optomechanics has allowed cooling of mesoscopic mechanical oscillators via dynamic backaction provided by the parametric coupling to either an optical or an electrical resonator. Here we analyze the occurrence of normal-mode splitting in backaction cooling at high input power. We find that a hybridization of the oscillator's motion with the fluctuations of...
متن کاملCavity optomechanics: back-action at the mesoscale.
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, givi...
