Nanomechanics has brought mesoscopic physics into the world of vibrations. Because
nanomechanical systems are small, fluctuations are significant, the vibrations already …

Fault detection is a key tool to ensure the safety and reliability of machinery. In machinery
fault detection, signal processing methods are extensively applied to extract fault …

Driven non-linear resonators can display sharp resonances or even multistable behaviours
amenable to induce strong enhancements of weak signals. Such enhancements can make …

We report the first observation of non-Markovian stochastic resonance (SR), and we
discover that memory effects in the nonlinearity extremely enlarge the SR bandwidth. Our …

Exceptional points (EPs)—spectral singularities of non-Hermitian linear systems—have
recently attracted interest for sensing. While initial proposals and experiments focused on …

Coupled nonlinear oscillators can present complex spatiotemporal behaviors. Here, we
report the coexistence of coherent and incoherent domains, called chimera states, in an …

The Duffing oscillator is a nonlinear extension of the ubiquitous harmonic oscillator and as
such plays an outstanding role in science and technology. Experimentally, the system …

The interferometric control of dissipation in a two-port system is a fruitful concept enabling
the enhancement or cancellation of the input amplitudes as a function of their relative …

We propose a novel methodology to estimate parameters characterizing a weakly nonlinear
Duffing oscillator represented by an optically levitating nanoparticle. The method is based …

Vibrational resonance is a generic phenomenon found in many different bistable systems
whereby a weak low-frequency signal is amplified by use of an additional nonresonant high …
