Response of parametrically driven nonlinear coupled oscillators with application to micromechanical and nanomechanical resonator arrays
The response of a coupled array of nonlinear oscillators to parametric excitation is calculated in the weak nonlinear limit using secular perturbation theory. Exact results for small arrays of oscillators are used to guide the analysis of the numerical integration of the model equations of motion for large arrays. The results provide a qualitative explanation for a recent experiment @Buks and R...
متن کاملNonlinear Switching Dynamics in a Nanomechanical Resonator
The oscillatory response of nonlinear systems exhibits characteristic phenomena such as multistability [1], discontinuous jumps [2, 3] and hysteresis [3]. These can be utilized in applications leading, e.g., to precise frequency measurement [4], mixing [5], memory elements [6, 7], reduced noise characteristics in an oscillator [8] or signal amplification [9, 10, 11, 12]. Approaching the quantum...
متن کاملMass detection with a nonlinear nanomechanical resonator.
Nanomechanical resonators having small mass, high resonance frequency, and low damping rate are widely employed as mass detectors. We study the performance of such a detector when the resonator is driven into a region of nonlinear oscillations. We predict theoretically that in this region the system acts as a phase-sensitive mechanical amplifier. This behavior can be exploited to achieve noise ...

Nonlinear Damping in Nanomechanical Beam Oscillator
We investigate the impact of nonlinear damping on the dynamics of a nanomechanical doubly clamped beam. The beam is driven into nonlinear regime and the response is measured by a displacement detector. For data analysis we introduce a nonlinear damping term to Duffing equation. The experiment shows conclusively that accounting for nonlinear damping effects is needed for correct modeling of the ...
