normal mode splitting and antibunching in stokes and anti stokes processes in cavity optomechanics radiation pressure induced four wave mixing cavity optomechanics
Physical Review A, 2010Co-Authors: Sumei Huang, G S AgarwalAbstract:We study Stokes and anti-Stokes processes in cavity optomechanics in the regime of strong coupling. The Stokes and anti-Stokes signals exhibit prominently the normal-mode splitting. We report gain for the Stokes signal. We also report lifetime splitting when the pump power is less than the critical power for normal-mode splitting. The nonlinear Stokes processes provide a useful method for studying the strong-coupling regime of cavity optomechanics. We also investigate the correlations between the Stokes and the anti-Stokes photons produced spontaneously by the optomechanical system. At zero temperature, our nanomechanical system leads to the correlations between the spontaneously generated photons exhibiting photon antibunching and those violating the Cauchy-Schwartz Inequality.

average dwell time approach to l2 gain control synthesis of switched linear systems with time delay in detection of switching signal
Iet Control Theory and Applications, 2009Co-Authors: D Xie, Q WangAbstract:For switched linear systems with time delay in detection of switching signal, the authors investigate its L 2 gain control synthesis problem via off-line-type switched state feedback by average dwell-time approach, that is identifying an average dwell time to guarantee that switched system is exponentially stable with an L 2 gain less than chi. The authors first establish an estimation on the state transition matrix of switched systems. Then, based on this concise estimation and some famous mathematical inequalities such as Minkowski's integral Inequality and Cauchy-Schwartz Inequality, the authors prove that there exists a switched state-feedback controller such that switched system has an L 2 gain less than chi for any switching signal with average dwell time greater than a given constant. Finally, an example is given to illustrate our results. Our results complement and generalise those results given in the works of Xie and Wang, Ji et al . and Xie and Chen.
