We present a study of a collision--less plasma governed by the Vlasov--Poisson system of equations in one space and one velocity dimension; the plasma is subject to initial density perturbations and to both periodic and non periodic space boundary co

We study the dynamics of phase space holes in a non-collisional plasma by numerical integration of the one-dimensional Vlasov equation. The plasma is bounded and connected to vacuum by two interfaces, which gives rise to non- periodic boundary condit

A drift-kinetic Eulerian Vlasov code with fluid equations for the ions is used to study the collisionless diffusion of particles and current across a magnetic field for the case of an electron beam injected near the edge of a two-dimensional magnetiz

The numerical integration of the Vlasov equation possessing an invariant
Autor: Alain Ghizzo, E. Fijalkow, Giovanni Manfredi, M. Shoucri, Marc R. Feix, Pierre Bertrand
Publikováno v: Journal of Computational Physics. 121:298-313
A new method for the numerical integration of the Vlasov equation is presented, which can be applied whenever its characteristics possess an exact invariant. It consists in expressing the distribution function in terms of the invariant itself. The di

Explicit analytical solution of the nonlinear Vlasov–Poisson system
Autor: Swadesh M Mahajan, E. Fijalkow, V. Škarka
Publikováno v: Physics of Plasmas. 1:528-540
In order to describe the time evolution of an inhomogeneous collisionless plasma, the nonlinear Vlasov equation is solved perturbatively, using the subdynamics approach and the diagrammatic techniques. The solution is given in terms of a double pertu

Study of the diffusion across a magnetic field in a beam–plasma interaction using a drift‐kinetic Vlasov code
Autor: Pierre Bertrand, A. Ghizzo, E. Fijalkow, Magdi Shoucri, Marc R. Feix
Publikováno v: Physics of Fluids B: Plasma Physics. 5:4312-4326
A drift‐kinetic Eulerian Vlasov code, with fluid equations for the ions, is developed to study the problem of the injection of an electron beam into a two‐dimensional magnetized plasma, often referred to as direct current (dc) helicity injection.

An Eulerian Code for the Study of the Drift-Kinetic Vlasov Equation
Autor: Pierre Bertrand, Marc R. Feix, A. Ghizzo, E. Fijalkow, M. Shoucri
Publikováno v: Journal of Computational Physics. 108:105-121
An Eulerian code is developed to study the drift-kinetic Vlasov equation in a strong magnetic field. This is of interest in relation to studies on the E × B instabilities, as, for instance, the hydrodynamical Kelvin-Helmholtz (KH) instabilities and
