A fully non-linear multi-species Fokker-Planck-Landau collision operator for simulation of fusion plasma

Fusion edge plasmas can be far from thermal equilibrium and require the use of a non-linear collision operator for accurate numerical simulations. In this article, the non-linear single-species Fokker-Planck-Landau collision operator developed by Yoon and Chang [Phys. Plasmas 21, 032503 (2014)] is generalized to include multiple particle species. The finite volume discretization used in this wo...

Linearized quantum and relativistic Fokker-Planck-Landau equations

After a recent work on spectral properties and dispersion relations of the linearized classical Fokker-Planck-Landau operator 8], we establish in this paper analogous results for two more realistic collision operators: The rst one is the Fokker-Planck-Landau collision operator obtained by relativistic calculations of binary interactions , and the second is a collision operator (of Fokker-Planck...
