| Speaker | Lukas Novotny, Professor of Photonics at ETH Zurich and Professor of Optics and Physics at the University of Rochester, NY. L. Novotny did his diploma and doctoral degree ETH Zurich. His doctoral work was in collaboration with the IBM Research Laboratories and dealt with theoretical problems in near-field optics, for which he was awarded the ETH Medal. From 1996-99 he was a postdoctoral fellow at the Pacific Northwest National Laboratory, working on new schemes of single molecule detection and nonlinear spectroscopy. In 1999 he joined the faculty of the Institute of Optics where he started one of the first research programs with focus on nano-optics. Novotny is the author of the textbook 'Principles of Nano-Optics', which is currently in its second edition. He is a Fellow of the Optical Society of America and the American Association for the Advancement of Science. |

Abstract: I discuss our experiments with optically levitated nanoparticles in ultrahigh vacuum. Using both active and passive feedback techniques we cool the particle’s center-of-mass temperature to T ∼ 100µK and reach mean quantum occupation numbers of n ∼ 15. I show that mechanical quality factors of Q = 109can be reached and that damping is dominated by photon recoil heating. The vacuum-trapped nanoparticle forms an ideal model system for studying non-equilibrium processes, nonlinear interactions, and ultrasmall forces.
