Sensitive force-detection with optically-levitated microspheres in vacuum

Andrew A. Geraci, Scott B. Papp, John Kitching

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Optically levitated and cooled dielectric microspheres in vacuum show great promise as resonant force detectors with an expected sub-attonewton sensitivity. Hence, they can be used to investigate Casimir forces or for testing non-Newtonian gravity.
