Abstract

We describe recent experiments that have demonstrated cavity optomechanical cooling of the center-of-mass motion of nanospheres. The naturally charged silica spheres are levitated within vacuum using an overlapping optical and electrodynamical trap. Using this system we have cavity cooled trapped nano-spheres of radius 200nm from above room temperature to less than 10K in a vacuum of 10^-⁴ mbar.
