DECREASE OF THE FISHER INFORMATION FOR SOLUTIONS OF THE SPATIALLY HOMOGENEOUS LANDAU EQUATION WITH MAXWELLIAN MOLECULES

We give a direct proof of the fact that, in any dimension of the velocity space, Fisher's quantity of information is nonincreasing with time along solutions of the spatially homogeneous Landau equation for Maxwellian molecules. This property, which was first seen in numerical simulation in plasma physics, is linked with the theory of the spatially homogeneous Boltzmann equation.

Computational Simulation of Plasmas

This paper reviews the use of computational simulation in plasma physics. It describes a range of numerical models varying from particle models of low density collisionless plasmas to fluid models of high density collision-dominated plasmas. Some applications of these models, particularly to laser-produced and astrophysical plasmas, are described.

Particle code optimization on vector computers

Big particle codes routinely employed for plasma physics simulation use large amounts of computer time. Their optimization is therefore a must. In this paper we discuss proper organization of the particle pusher in order to take full advantage of the vectorization facilities offered by modern super computers. We show that this optimization is computer dependent and introduce a new method of vectorization that we compare with the two previously published ones.
