Abstract

I will describe a new program of measurements in fundamental physics using optically levitated dielectric microspheres. The focus of the talk will be the recently completed first search for new, gravity-like interactions at micron scale using this novel technique. I will also show an array of other results, including searches for millicharged particles, Chameleon fields and techniques to manipulate the various degrees of freedom of the trapped microspheres.
