Noise squeezing in a nanomechanical Duffing resonator.
We study mechanical amplification and noise squeezing in a nonlinear nanomechanical resonator driven by an intense pump near its dynamical bifurcation point, namely, the onset of Duffing bistability. Phase sensitive amplification is achieved by a homodyne detection scheme, where the displacement detector's output, which has a correlated spectrum around the pump frequency, is down-converted by m...
متن کاملNoise-enabled precision measurements of a duffing nanomechanical resonator.
We report quantitative measurements of the nonlinear response of a radio frequency mechanical resonator with a very high quality factor. We measure the noise-free transitions between the two basins of attraction that appear in the nonlinear regime, and find good agreement with theory. We measure the transition rate response to controlled levels of white noise, and extract the basin activation e...
متن کاملSignal amplification in NbN superconducting resonators via stochastic resonance
We exploit nonlinearity in NbN superconducting stripline resonators, which originates from local thermal instability, for studying stochastic resonance. As the resonators are driven into instability, small amplitude modulation (AM) signals are amplified with the aid of injected white noise. Simulation results based on the equations of motion for the system yield a good agreement with the experi...
متن کاملStochastic Resonance in a bistable nanomechanical beam
Stochastic resonance is a counter-intuitive con system induces coherent amplification of i mechanism for the cyclic recurrence of ice ag in a wide variety of macroscopic physical syst magnetoelastic ribbons, and neurophysiolog crickets and crayfish. Although it is fundam coherent signal amplification, stochastic reson systems. Here we report the observation nanomechanical silicon oscillators, w...
متن کاملStochastic Resonance Phenomenon of Two-coupled Duffing Oscillator and its Application on Weak Signal Detection
By taking two-coupled duffing oscillator system as the research object, the study found under the synergistic effect of weak periodic signal and noise, the two-coupled duffing oscillator system has typical stochastic resonance and even could achieve better output of stochastic resonance than single duffing oscillator. Based on this phenomenon, this paper proposes a new method to detect the weak...
