Random self-modulation of two-dimensional structures on a liquid surface during parametric excitation
Ezerskii A. B., Korotin P. I., Rabinovich M. I.
Experiments show that the transition to turbulence at the parametrically excited surface of a heavy liquid occurs through the development of a spatial and temporal modulation of two-dimensional wavelike structures (lattices). When the pump exceeds a certain critical level, the periodic modulation regime gives way to a random regime. The transition to chaos involves an intermittence: a formation of dislocations.
