Abstract Synchronized oscillators are ubiquitous in nature and engineering. Despite several models that have been proposed to treat synchronized oscillators beyond weak coupling, the widely accepted paradigm holds that synchronization occurs due to w

Abstract Nonlinear interactions between modes with eigenfrequencies that differ by orders of magnitude are ubiquitous in various fields of physics, ranging from cavity optomechanics to aeroelastic systems. Simplifying their description to a minimal m

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 mic

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

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

In doubly clamped curved mechanical beams, there are inherent hardening and softening nonlinearities. Thus, their frequency of oscillation is a non-monotonic function of the energy. However, for a sufficiently high energy level there is a zero-disper
Models for nonlinear vibrations commonly employ polynomial terms that arise from series expansions about an equilibrium point. The analysis of symmetric systems with cubic terms is very common, and the inclusion of asymmetric quadratic terms is known

In lieu of active feedback control in complex systems over long timeframes, nonlinear dynamics offers solutions to generate long-term responses. This type of control has been proposed for use in resonators that exhibit a plethora of complex dynamic b

This paper considers nonlinear interactions between vibration modes with a focus on recent studies relevant to micro- and nanoscale mechanical resonators. Due to their inherently small damping and high susceptibility to nonlinearity, these devices ha

We formulate and experimentally validate a theoretical reduced-order model for the transverse galloping of nonlinear structures, namely a pair of identical, parallel-oriented cantilever beams whose free ends are attached to square prisms. We derive t
