Abstract
A levitated non-spherical nanoparticle in a vacuum is ideal for studying quantum rotations and is an extremely sensitive torque and force detector. Here, we report optical levitation of a GHz rotating silica nanodumbbell in a vacuum at about 430 nm away from a sapphire surface. The rotating nanodumbbell near the surface demonstrate a torque sensitivity of (5.0 ± 1.1) × 10^(-26) NmHz^(−1/2) at room temperature. Moreover, we levitate a nanodumbbell near a gold nanograting and use it to probe the near-field intensity distribution beyond the optical diffraction limit. The system is promising to detect the Casimir torque.
