University of Rochester optics professor Nick Vamivakas and physics Ph.D. candidate Levi Neukirch perform experiments with optically levitated nanodiamonds contained inside a trapping chamber in Wilmott Hall June 14, 2013. The process allows researchers to test fundamental physics questions related to quantum mechanics as well as provide a tool to perform high sensitivity nanoscale force sensing. // photo by J.
