Measuring gravity at micron scale and other fun tricks with optically levitated microspheres

Prof. Giorgio Gratta, Stanford University

12/08 – 17h – quinta-feira

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.
