Cavity optomechanics with an optically levitated submicron particle — •Uroš Delić, Nikolai Kiesel, Florian Blaser, David Grass, Rainer Kaltenbaek, and Markus Aspelmeyer — Vienna Center for Quantum Science and Technology (VCQ), Faculty of Physics, University of Vienna, A-1090 Vienna, Austria

The center-of-mass motion of an optically levitated sub-micron dielectric particle, once decoupled from thermal environment, promises unprecedented high mechanical quality factors and a large force sensitivity [1]. Combined with an optical cavity this approach has been anticipated to allow room temperature quantum optomechanics [2]. We demonstrate experimentally the cavity-optomechanical control of a sub-wavelength sized particle and compare our results with a detailed theoretical description of the system. Current challenges and future extensions of the system towards high-Q operation are discussed.
