Optically Levitated Torque Sensor and Ultrafast Nanomechanical Rotor

We propose to optically levitate a nonspherical nanoparticle in vacuum to detect the quantum vacuum torque (Casimir torque). We have levitated nonspherical nanoparticles in vacuum and driven them to mechanically rotate at several hundred MHz.
