Spatiotemporal intermittency in the Faraday experiment

Abstract
The spectral fluctuations of random capillary wave fields appear to be intermittent. This intermittency is related to local creation and annihilation of coherent structures: ordered regions that have definite symmetry. Both the occurrence of non-Gaussian fluctuations and the existence of (quasi) long-range order question the applicability of a thermodynamic description of spatiotemporal chaos in two dimensions.
