Particle kinetic modelling of rarefied gases and plasmas

We show that Monte Carlo methods can be usefully applied to particle transport problems in the challenging conditions set up by the merging of two fields: rarefied gas dynamics and cold plasmas. The simulation of these systems, in fact, requires us to analyse the foundation of the method in order to develop transport modelling techniques that can take into account at the same time the non-equilibrium kinetics of the scattering medium. We demonstrate this point by providing examples extracted from the work of our group in the fields of cold plasmas, rarefied gas dynamics and coherent kinetics.
