"Phase transitions" in an array of parametric waves at the surface of an oscillating liquid
Levin B. V., Trubnikov B. A.
Recent experiments by Aleksandrov et al. on water in a vessel with a vibrating bottom revealed that regular structures with hexagonal or square cells and an array of parallel crests are formed on the surface of the water under certain conditions. The present letter offers a theory for this phenomenon which is induced by a parametric resonance.
