Parametric resonance for complex fields [PDF]
Physics Letters B, 2000 Recently, there have been studies of parametric resonance decay of oscillating real homogeneous cosmological scalar fields, in both the narrow-band and broad-band case, primarily within the context of inflaton decay and (p)reheating. However, many realistic models of particle cosmology, such as supersymmetric ones, inherently involve complex scalar ...

Quantum parametric resonance [PDF]
Journal of Physics A: Mathematical and General, 2002 The quantum mechanical equivalent of parametric resonance is studied. A simple model of a periodically kicked harmonic oscillator is introduced which can be solved exactly. Classically stable and unstable regions in parameter space are shown to correspond to Floquet operators with qualitatively different properties.

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 ...

Parametric Resonance in Networked Oscillators [PDF]
IEEE Transactions on Control of Network SystemsWe investigate parametric resonance in oscillator networks subjected to periodically time-varying oscillations in the edge strengths. Such models are inspired by the well-known parametric resonance phenomena for single oscillators, as well as the potential rich phenomenology when such parametric excitations are present in a variety of applications like

Parametric resonance in concrete beam-columns
Latin American Journal of Solids and StructuresA dynamic instability, called parametric resonance, is exhibited by undampedelastic beam-columns when under the action of pulsating axial force. The scope of the existing theory of parametric resonance is restricted to physically linear beam-columns ...

Coordinated optical and radar observations of ionospheric pumping for a frequency pass through the second electron gyroharmonic at HAARP [PDF]
, 2007 On 4 February 2005, the High-frequency Active Auroral Research Program (HAARP) facility was operated in O and X mode while pointing into the magnetic zenith to produce artificial optical emissions in the ionospheric F layer. The pump frequency was set to

Stability Analysis of Randomly Excited Ship Parametric Roll Resonance
, 2017 In this paper, ship stability of randomly excited parametric roll resonance is studied. Parametric roll resonance will lead to severe roll motion and even capsize. Studies on parametric roll resonance have many challenges for the randomness and nonlinear.

Forward flight of birds revisited. Part 2: short-term dynamic stability and trim [PDF]
Royal Society Open Science, 2014 Thrust generation by flapping is accompanied by alternating pitching moment. On the down-stroke, it pitches the bird down when the wings are above its centre of gravity and up when they are below; on the up-stroke, the directions reverse.
