Quadratic optomechanical cooling of a cavity-levitated nanosphere
N. P. Bullier, A. Pontin, P. F. Barker
We report on cooling the center-of-mass motion of a nanoparticle due to a purely quadratic coupling between its motion and the optical field of a high finesse cavity. The resulting…
Optical levitation using broadband light
A. T. M. Anishur Rahman, P. F. Barker
The ability to create dynamic, tailored optical potentials has become important across fields ranging from biology to quantum science. We demonstrate a method for the creation of a…
Optical levitation of high purity nanodiamonds in vacuum without heating
A. C. Frangeskou, A. T. M. A. Rahman, L. Gines +4
Levitated nanodiamonds containing nitrogen vacancy centres in high vacuum are a potential test bed for numerous phenomena in fundamental physics. However, experiments so far have b…
Doppler cooling a microsphere
P. F. Barker
Doppler cooling the center-of-mass motion of an optically levitated microsphere via the velocity dependent scattering force from narrow whispering gallery mode (WGM) resonances is…
