DESCRIPTION:Lukas Novotny\, Professor of Photonics at ETH Zurich and Prof
 essor of Optics and Physics at the University of Rochester\, NY. L. Novot
 ny did his diploma and doctoral degree ETH Zurich. His doctoral work was i
 n collaboration with the IBM Research Laboratories and dealt with theoreti
 cal 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 Natio
 nal Laboratory\, working on new schemes of single molecule detection and n
 onlinear spectroscopy. In 1999 he joined the faculty of the Institute of O
 ptics where he started one of the first research programs with focus on na
 no-optics. Novotny is the author of the textbook 'Principles of Nano-Optic
 s'\, which is currently in its second edition.  He is a Fellow of the Opt
 ical Society of America and the American Association for the Advancement o
 f Science.\nAbstract: 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 ∼ 10
 0µK and reach mean quantum occupation numbers of n ∼ 15. I show that me
 chanical quality factors of Q = 109can be reached and that damping is domi
 nated by photon recoil heating. The vacuum-trapped nanoparticle forms an i
 deal model system for studying non-equilibrium processes\, nonlinear inter
 actions\, and ultrasmall forces.
