Parametric Resonance of Optically Trapped Aerosols [PDF]
The Brownian dynamics of an optically trapped water droplet are investigated across the transition from over to under-damped oscillations. The spectrum of position fluctuations evolves from a Lorentzian shape typical of over-damped systems (beads in liquid solvents), to a damped harmonic oscillator spectrum showing a resonance peak. In this later under-

Parametric Symmetry Breaking in a Nonlinear Resonator [PDF]
Much of the physical world around us can be described in terms of harmonic oscillators in thermodynamic equilibrium. At the same time, the far from equilibrium behavior of oscillators is important in many aspects of modern physics. Here, we investigate a resonating system subject to a fundamental interplay between intrinsic nonlinearities and a ...

Parametric Resonance in Quantum Field Theory [PDF]
We present the first study of parametric resonance in quantum field theory from a complete next-to-leading order calculation in a 1/N-expansion of the 2PI effective action, which includes scattering and memory effects. We present a complete numerical solution for an O(N)-symmetric scalar theory and provide an approximate analytic description of the ...

Magnetoelastic Principal Parametric Resonance of a Rotating Electroconductive Circular Plate
Nonlinear principal parametric resonance and stability are investigated for rotating circular plate subjected to parametric excitation resulting from the time-varying speed in the magnetic field.

Parametric Resonance in the Logistic Equation with Delay under a Two-Frequency Perturbation
A logistic equation with a delay feedback circuit and with periodic perturbation of parameters is considered. The problem parameters (a coefficient of the linear growth and a delay) are chosen close to the critical values at which a cycle is bifurcated ...

Experience from Parametric Rolling of Ships
This chapter reviews three recent full-scale events with parametric rolling for Ro–Ro Large Car and Truck Carriers (LCTC). The events represent three principally different modes of parametric rolling: principal parametric resonance where the period of ...

A Real-Time Detection System for the Onset of Parametric Resonance in Wave Energy Converters
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 ...

Since the discovery of parametric anti-resonance, parametric excitation has also become more prominent for its stabilizing properties. While resonance and anti-resonance are mostly studied individually, there are systems where both effects appear ...

Parametric Resonance of Dynamic Systems
The Bachelor’s Thesis deals with the parametric resonance which is investigated from the physical point of view by means of pendulum models, for which the equation of motion has been developed and subsequent modelling has been performed.
