Amplitude stabilization in a synchronized nonlinear nanomechanical oscillator

In contrast to the well-known phenomenon of frequency stabilization in a synchronized noisy nonlinear oscillator, little is known about its amplitude stability. this paper, we investigate experimentally and theoretically evolution stability nanomechanical self-sustained oscillator that with an external harmonic drive. We show phase difference between tones plays critical role on level, demonstrate strongly regime, fluctuations are reduced considerably. These findings bring light new facet synchronization phenomenon, extending range applications beyond field clock-references suggesting means enhance
