Work fluctuations in a nonlinear micromechanical oscillator driven far from thermal equilibrium
P. Zhou, X. Dong, C. Stambaugh +1
We explore fluctuation relations in a periodically driven micromechanical torsional oscillator. In the linear regime where the modulation is weak, we verify that the ratio of the w…
From membrane-in-the-middle to mirror-in-the-middle with a high-reflectivity sub-wavelength grating
Corey Stambaugh, Haitan Xu, Utku Kemiktarak +2
We demonstrate a "membrane in the middle" optomechanical system using a silicon nitride membrane patterned as a subwavelength grating. The grating has a reflectivity of over 99.8%,…
Switching path distribution in multi-dimensional systems
H. B. Chan, M. I. Dykman, C. Stambaugh
We explore the distribution of paths followed in fluctuation-induced switching between coexisting stable states. We introduce a quantitative characteristic of the path distribution…
Paths of fluctuation induced switching
H. B. Chan, M. I. Dykman, C. Stambaugh
We demonstrate that the paths followed by a system in fluctuation-activated switching form a narrow tube in phase space. A theory of the path distribution is developed and its dire…
Activation barrier scaling and crossover for noise-induced switching in a micromechanical parametric oscillator
H. B. Chan, C. Stambaugh
We explore fluctuation-induced switching in a parametrically-driven micromechanical torsional oscillator. The oscillator possesses one, two or three stable attractors depending on…
Fluctuation-enhanced frequency mixing in a nonlinear micromechanical oscillator
H. B. Chan, C. Stambaugh
We study noise-enhanced frequency mixing in an underdamped micromechanical torsional oscillator. The oscillator is electrostatically driven into bistability by a strong, periodic v…
