Spatiotemporal intermittency in the Faraday experiment

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
