A Real-Time Detection System for the Onset of Parametric Resonance in Wave Energy Converters
Journal of Marine Science and Engineering, 2020 Parametric resonance is a dynamic instability due to the internal transfer of energy between degrees of freedom. Parametric resonance is known to cause large unstable pitch and/or roll motions in floating bodies, and has been observed in wave energy ...

Plasmonic Parametric Resonance [PDF]
2018 IEEE Photonics Conference (IPC), 2018 We introduce the concept of Plasmonic Parametric Resonance (PPR) as a novel way to amplify high angular momentum plasmonic modes of nanoparticles by means of a simple uniform optical pump. In analogy with parametric resonance in dynamical systems, PPR originates from the temporal modulation of one of the parameters governing the evolution of the state ...

Numerical investigation of parametric resonance due to hydrodynamic coupling in a realistic wave energy converter. [PDF]
Nonlinear Dyn, 2020 Representative models of the nonlinear behavior of floating platforms are essential for their successful design, especially in the emerging field of wave energy conversion where nonlinear dynamics can have substantially detrimental effects on the ...

Parametric-Resonance Entangling Gates with a Tunable Coupler [PDF]
Physical Review Applied, 2021 High-fidelity parametric gates have been demonstrated with superconducting qubits via rf flux modulation of the qubit frequency. The modulation however leads to renormalization of the bare qubit-qubit coupling, thereby reducing the gate speed.

Graviton to photon conversion via parametric resonance [PDF]
Physics of the Dark Universe, 2022 We study the parametric resonance excitation of the electromagnetic field by a gravitational wave. We show that there is narrow band resonance. For an electromagnetic field in the vacuum the resonance occurs only in the second band, and its strength is ...

Coexisting attractors in floating body dynamics undergoing parametric resonance
Acta Mechanica, 2022 This study pertains to analysing the dynamical behaviour of a floating body undergoing parametric resonances. A simple vertical cylinder, representing a classical spar-buoy, is considered, limiting its motion to heave and pitch degrees of freedom.

Wavenumber lock-in and spatial parametric resonance in convection
Journal of Fluid Mechanics, 2022 Analysis of convection driven by spatial periodic heating shows a wealth of responses due to Prandtl number dependence. The primary convection is delineated by the heating wavenumber and the secondary convection is characterized by the critical ...

How to suppress exponential growth—on the parametric resonance of photons in an axion background [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Axion-photon interactions can lead to an enhancement of the electromagnetic field by parametric resonance in the presence of a cold axion background, for modes with a frequency close to half the axion mass.

Tuning nonlinear damping in graphene nanoresonators by parametric–direct internal resonance
Nature Communications, 2021 Mechanical sources of nonlinear damping play a central role in modern physics, from solid-state physics to thermodynamics. The microscopic theory of mechanical dissipation suggests that nonlinear damping of a resonant mode can be strongly enhanced when ...
