Dynamical properties of test particles in stochastic electromagnetic fields

In this work, we studied the 2D dynamics of test particles in electromagnetic fields gener-ated by a random distribution of oscillating ‘‘clouds” located in the (x; y) plane. Owing to anon-stationarity of the system, we investigated the relationship between the diffusion inthe real space and in the velocity space when some parameters of the model are changed,as for example the oscillation frequency and the typical extension of the clouds. We foundthat for some values of these parameters particles increase their energy and undergosuperdiffusion in the real space.
