SYNCHRONIZATION OF CHAOS AND THE TRANSITION TO WAVE TURBULENCE

International Journal of Bifurcation and Chaos, 2012
We investigated the transition to wave turbulence in a spatially extended three-wave interacting model, where a spatially homogeneous state undergoing chaotic dynamics undergoes spatial mode excitation. The transition to this weakly turbulent state can be regarded as the loss of synchronization of chaos of mode oscillators describing the spatial ...

Traveling waves and chaos in thermosolutal convection

Physical Review A, 1987
Numerical experiments on two-dimensional thermosolutal convection reveal oscillations in the form of traveling, standing, modulated, and chaotic waves. Transitions between these wave forms and steady convection are investigated and compared with theory.

Genuine electromagnetic wave chaos

Physical Review E, 1995
The existence of genuine electromagnetic wave chaos is predicted. The prediction is based on a general nonlinear mechanism that destroys the superposition principle in case the electromagnetic field is allowed to interact dynamically with its boundary. Strong support for this prediction is derived from various model calculations.

Controlling chaos in spin-wave instabilities

Physical Review Letters, 1991
A microwave-pumped spin-wave-instability experiment is used to demonstrate that chaos can be controlled by a small periodic perturbation of an available system parameter, as recently proposed by Ott, Grebogi, and Yorke. The experiment is performed in an yttrium-iron-garnet sphere in the subsidiary-resonance configuration with a small modulation in the ...

Chaos-induced intensification of wave scattering

Physical Review E, 2005
Sound-wave propagation in a strongly idealized model of the deep-water acoustic waveguide with a periodic range dependence is considered. It is investigated how the phenomenon of ray and wave chaos affects the sound scattering at a strong mesoscale inhomogeneity of the refractive index caused by the synoptic eddy.

Bifurcations, chaos and control of chaos in spin-wave instabilities

Journal of Magnetism and Magnetic Materials, 1992
Abstract An experimental study of microwave pumped spin-wave instabilities in YIG reveals new types of bifurcations and the possibility of controlling chaos with a small perturbation in a system parameter.

Wave chaos in singular quantum billiard

Physical Review Letters, 1990
Summary: We present a solvable singular quantum billiard which displays fully developed wave chaos. Its level statistics is investigated and proved to coincide with predictions of the Gaussian orthogonal ensemble of random matrices. The corresponding wave functions are shown to be well approximated by a Gaussian ransom variable.

A possible plasma wave chaos

Physics of Fluids B: Plasma Physics, 1990
A model equation for the ionization wave (Duffing’s equation) is studied. The system shows chaotic behavior via an intermittent route to chaos. It is left for experimentalists to devise experiments to test the theoretical predictions.

Wave Chaos in Elastodynamics

2001
Recent years have demonstrated that ultrasonic waves in solids permit investigations of wave chaos, reverberation and multiple scattering that complement those of microwaves, optics and electronics. The large quality factors that can be achieved with elastic waves, their relatively slow wave speed, and their good impedance mismatch with the laboratory,

Wave Chaos and Chaotic Transmission of Waves

1997
Abstract : Our goal is to develop an analytical and numerical approach to diagnose arrival sound waves from long-distanced sources on the basis of the most advanced methods of dynamics that include ray dynamics, wave dynamics reconstruction on the basis of ray dynamics, specific asymptotic solutions in the short-wave approximation, and specific ...
