The high plasma temperatures expected at reactor conditions in magnetic confinement
fusion toroidal devices suggest that near-marginal operation could be a reality in future …

Lévy flights are paradigmatic generalised random walk processes, in which the independent
stationary increments—the'jump lengths'—are drawn from an-stable jump length distribution …

Context. In-situ spacecraft observations recently suggested that the transport of energetic
particles accelerated at heliospheric shocks can be anomalous, ie the mean square …

The methanol mass transfer in the mesoporous silica and alumina/zeolite H-ZSM-5 grains
has been studied. We demonstrate that the methanol diffusion is characterized as a time …

In the last few years it has been demonstrated, both by data analysis and by numerical
simulations, that the transport of energetic particles in the presence of magnetic turbulence …

The TORPEX basic plasma physics device at the Center for Plasma Physics Research
(CRPP) in Lausanne, Switzerland is described. In TORPEX, simple magnetized toroidal …

Lévy stochastic processes, with noise distributed according to a Lévy stable distribution, are
ubiquitous in science. Focusing on the case of a particle trapped in an external harmonic …

The understanding of the transport of suprathermal ions in the presence of turbulence is
important for fusion plasmas in the burning regime that will characterize reactors, and for …

In this paper, we consider the backward problem for diffusion equation with space-fractional
Laplacian. In order to overcome the ill-posedness of the backward problem, we propose a …

This article investigates the correlation between the Kappa and Lévy distributions via two
approaches of the Klein–Kramers equation. The first approach illustrates the velocity …
