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.

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 ...

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 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.

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.

Controlling chaos in nonlinear three-wave coupling

Physical Review E, 1996
It is shown that the chaotic orbits in the saturated states of nonlinear three-wave coupling can be controlled by applying a new resonance, via a small sinusoidal anti-Stokes wave, to the system. For a given set of linear frequency mismatch and growth-damping parameters, any desired periodic orbit can be achieved by a proper adjustment of the amplitude

Spatiotemporal Chaos in Interfacial Waves

1991
Spatiotemporal chaos occurs in many hydrodynamic systems. This state is distinguished from temporal chaos by at least partial loss of coherence between different spatial regions, and from fully developed turbulence by the absence of a cascade. Several experimental and theoretical examples of spatiotemporal chaos are briefly reviewed.

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.

Strange attractors in spin-wave chaos

Physica A: Statistical Mechanics and its Applications, 1990
Abstract Interacting spin-wave modes pumped by microwave radiation in magnetic crystals display a rich variety of nonlinear dynamic effects such as self-oscillations, intermittency, period multiplication bifurcations and chaos. We review recent experiments in this area and present measurements to characterize strange attractors at the onset of chaos ...
