A two-dimensional system of non-locally coupled complex Ginzburg-Landau
oscillators is investigated numerically for the first time. As already known
for the one-dimensional case, the system exhibits anomalous spatio-temporal
chaos characterized by power-law spatial correlations. In this chaotic regime,
the amplitude difference between neighboring elements shows temporal noisy
on-off intermittency. The system is also spatially intermittent in this regime,
which is revealed by multi-scaling analysis; the amplitude field is
multi-affine and the difference field is multi-fractal. Correspondingly, the
probability distribution function of the measure defined for each field is
strongly non-Gaussian, showing scale-dependent deviations in the tails due to
intermittency.Comment: 9 pages, 14 figures, submitted to Chao
