✦ Synopsis

In this work, we studied the 2D dynamics of test particles in electromagnetic fields generated by a random distribution of oscillating ''clouds" located in the (x; y) plane. Owing to a non-stationarity of the system, we investigated the relationship between the diffusion in the 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 found that for some values of these parameters particles increase their energy and undergo superdiffusion in the real space.
