Explore the non-linear classical dynamics of a micro-mechanical cantilever driven by radiation pressure in a high-finesse optical cavity. The interaction between the cantilever motion and cavity resonance frequency results in stable oscillation islands with varied amplitudes and an intriguing optical spring potential energy effect. Collaborated research with Florian Marquardt and Jack Harris at Yale University sheds light on the feedback effects and system behavior. Outreach activities include the Yale University Physics Olympics, educational support for undergraduate research by Joe Chen and engagement with graduate students and post-doctoral fellows such as George Mias, Lev Bishop, Terri Yu, Jack Challis, Mara Daniels, A. Durst, K. Sengupta, A. Blais, J. Gambetta, M. Vavilov, V. Oganesyan, and A. Andre.

  1. Theory of Opto-Mechanical Systems S. M. Girvin Yale University NSF DMR-0342157 In collaboration with Florian Marquardt and experimental colleague Jack Harris, we have studied the non-linear classical dynamics of a micro-mechanical cantilever driven by the radiation pressure in a high finesse optical cavity. Motion of the cantilever changes the resonance frequency of the cavity and hence the radiation pressure. This feedback effect leads to large number of ‘islands’ of stable oscillation of different amplitudes (in green in middle figure) and a non-trivial ‘optical spring’ effective potential energy for the cantilever (blue inset in lower figure). http://www.arxiv.org/abs/condmat/0502561
