Primary resonance of piezoelectric resonators

1996 IEEE Ultrasonics Symposium. Proceedings, 2002
It is found that the nonlinear behavior of piezoelectric resonators is more complicated than that predicted by previous theories. Actually the resonators work as parametrically excited vibration systems. Mode-coupled equations are obtained by means of the boundary integration. The method of multiple scales is used to solve the equations.

Stochastic Resonance as aBona FideResonance

Physical Review Letters, 1995
Stochastic resonance in a bistable potential is fully characterized as a synchronization effect of the hopping mechanism induced by the external periodic bias. Most notably, synchronization is shown to attain a maximum by increasing the forcing frequency close to the relevant switching rate, thus revealing a bona fide resonant process.

Ultrasensitive force detection with a nanotube mechanical resonator.

Nature Nanotechnology, 2013
Since the advent of atomic force microscopy, mechanical resonators have been used to study a wide variety of phenomena, including the dynamics of individual electron spins, persistent currents in normal metal rings and the Casimir force.

Resonant quasi-resonant solitons [PDF]

Bulletin of the Russian Academy of Sciences: Physics, 2012
Propagation of an optical pulse in a set of transitions created by simple Zeeman splitting is investigated. It is shown that resonant and nonresonant circularly polarized components repel one another, while a coupled soliton state can be formed only between quasi-resonant components whose planes of polarization rotate in opposite directions.

If It's Resonance, What Is Resonating?

Journal of Chemical Education, 2006
The resonance terminology that accompanies use of more than one Lewis-type structure to describe delocalized bonding in molecules has been leading students astray for more than half a century. In this article I review the origin of the terminology and how the original usage has evolved to reduce confusion.

Resonances in scattering by a resonator

Let \(\Omega\) be an exterior of a bounded domain. The self-adjoint operator \(H=-\Delta\) with Dirichlet boundary conditions on \(\partial \Omega\) is studied in \(L^ 2(\Omega)\). A resonance \(\phi\in L^ 2(\Omega)\) is defined as a vector which is concentrated in some bounded domain \(B\subset \Omega\) and such that the spectral measure \((E_ H ...

Nonlinear Resonance and Resonance Overlapping

2018
Higher-order components in the magnetic field in a ring introduce nonlinear terms into the Hamiltonian and generate nonlinear resonances. This can lead to complicated motion for particles with large amplitudes of betatron oscillations. We derive the resonant structure in the phase space due to a sextupole magnet when the fractional part of the tune is ...
