We study the cooling of a dielectric nanoscale particle trapped in an optical cavity. We derive the frictional force for motion in the cavity field and show that the cooling rate is proportional to the square of oscillation amplitude and frequency. Both the radial and axial components of the center-of-mass motion of the trapped particle, which are coupled by the cavity field, are cooled. This motion is analogous to two coupled but damped pendulums. Our simulations show that the nanosphere can be cooled to ${e}^{\ensuremath{-}1}$ of its initial momentum over time scales of hundredths of milliseconds.

- Biological measurement beyond the quantum limit (2012, background): “his technique is in optomechanical experiments with trapped levitating particles. Recent proposals predict that it may be possible to control the quantum mechanical state of such levitating particles (32,33). We have demonstrated that squeezing can be focused robustly in an optical trap. Introducing”
