The time evolution of (red line—upper curve) and (blue line—lower curve) [Eq. (20)]. The numerical error (black line—middle curve), given by the sum of these two contributions, is of the order of .
Two-dimensional polar contour of the number density (left panels) and the vorticity (right panels) at three different times, namely (upper panels), (middle panels), and (lower panels).
Samples of the time evolution of radial flux at three locations of the domain, namely (upper panel), (middle panel), and (lower panel) at .
Two-dimensional images of a single burst (left panel) and the corresponding electrostatic potential (right panel). In the right panel, the solid line contour indicates , while the dotted line contour indicates .
In the left panel, the time evolution of a burst as measured by a “probe” located at and is shown. In the right panel, a burst as a function of at is shown, detected at three different times, namely (curve a), (curve b), (curve c).
The large-scale profile of density (upper panel), and the standard deviation (lower panel).
Probability density functions of radial flux at three different radial locations: (curve a), (curve b), and (curve c).
PDF of the burst size (see text for definition) at (a) and (b) in double-logarithmic plots. This quantity measures the bursts' energy.
PDF of waiting times at (a) and (b) in double-logarithmic plots.
PDF of duration times at (a) and (b) in double-logarithmic plots.
Third-order mixed correlations at three different radial positions (symbols) (, , and , as shown in the figure legend) and the best-fit curves representing the Taylor logarithmic development described in Eq. (25) (full lines).
Parameters of fits reported in Fig. 11.
