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…
Supernarrow spectral peaks near a kinetic phase transition in a driven, nonlinear micromechanical oscillator
C. Stambaugh, H. B. Chan
We measure the spectral densities of fluctuations of an underdamped nonlinear micromechanical oscillator. By applying a sufficiently large periodic excitation, two stable dynamical…
