Spinning, scanning, and other fun tricks with optically levitated microspheres (Conference Presentation)
Author(s): Giorgio Gratta

Paper Abstract

Over the years, Ashkin's pioneering work on laser trapping of small particles has been exploited to study many phenomena in liquid suspensions, leading to advances in biophysics and polymer science. Could trapping in vacuum lead to advances on a similar scale in fundamental physics? In this talk I will describe work originally intended to improve our ability to test gravity at sub-100um scale. Towards this lofty goal, many manipulation techniques have been developed, some of which are interesting in their own right. The arsenal of tricks being assembled can indeed be applied to solve very hard experimental problems in fundamental physics.
