  • Nonlinear dissipation is frequently observed in nanomechanical resonators, but its microscopic origin remains unclear. Here, nonlinear damping is found to be enhanced in graphene nanodrums close to internal resonance conditions, providing insights on the mechanisms at the basis of this phenomenon.

  • Feedback control applied to mechanical resonators can lead to the formation of various complex dynamic behaviors. Here the authors demonstrate flexible and controllable switching between dynamical structures in the response of harmonically driven micro-mechanical resonators.

  • Synchronization between self-sustained oscillators is ubiquitous in nature and engineering, and it is generally accepted to occur due to weak interactions between the oscillating objects. The authors challenge this paradigm by presenting a theoretical higher-order phase model for non-weak coupling validated through experiments.

  • Nonlinear interactions between modes with eigenfrequencies that differ by orders of magnitude occur in several physical systems. This article provides a simple conceptual model of these interactions, and uses this model to design tunable frequency combs.

  • Synchronization, a ubiquitous phenomenon in nature, has been extensively studied from the frequency point of view for micro- and nano-electromechanical systems, but less so when amplitude stability is concerned. The authors investigate, theoretically and experimentally, the amplitude stabilization in an externally harmonic drive synchronized noisy nonlinear oscillator, showcasing the effect of the amplitude noise reduction in these devices.
