Note that there is another ingredient that may be essential to explain deviations from the standard transport model: [[Self-Organised_Criticality|self-organisation]]; we will not discuss this here.


Another approach is to test whether non-diffusive transport phenomena actually occur in simulations and experiment. To do so, ''tracer particles'' are injected into the plasma fluid, and their evolution is followed in time. Since the tracer trajectories can be analyzed by means of several analysis techniques, e.g. by calculating the particle distribution probability function, or by detecting velocity correlations along trajectories.  The application of this method has yielded clear indications that plasma turbulence induces non-diffusive transport in simulations.
