In order to study the transport of charged particles (ions, electrons) or dust particles in
tokamak plasma, we have used the numerical simulations method based on the TURBO …

We calculate the diffusion coefficients for ions moving in a prescribed electromagnetic field.
The field is considered to be a superposition of an electrostatic stochastic field and a space …

In the present paper the decorrelation trajectory method has been used in order to calculate
some averaged quantities of interest for stochastic anisotropic magnetic field lines in a …

In this paper we consider a class of discrete dynamical systems obtained through mapping
technique from 3/2 dof Hamiltonian systems and we present some results concerning the …

We study the trajectories of the particle in a combined electrostatic and magnetic stochastic
fields. Interesting results were obtained for different regimes characterized by the magnetic …
