Searching for new physics using optically levitated sensors

WebHigh frequency gravitational wave detection with optically levitated nanoparticles: an update on the LSD (levitated sensor detector). In J. Scheuer, & S. M. Shahriar (Eds.), Optical and Quantum Sensing and Precision Metrology II [120160A] (Proceedings of SPIE - The International Society for Optical Engineering; Vol. 12016). WebOptically levitated nanospheres in vacuum serve as a powerful probe for precision force sensing due to their excellent decoupling from the environment. We describe a method for 3-D scanning force sensing of a conducting surface with a levitated nanosphere. 3-D control of a nanosphere near a conductive surface could enable attonewton-level ... css hn
