Structure-preserving particle methods for the Landau collision operator using the metriplectic framework
Sandra Jeyakumar, Michael Kraus, Matthew J. Hole +1
We present a novel family of particle discretisation methods for the nonlinear Landau collision operator. We exploit the metriplectic structure underlying the Vlasov-Maxwell-Landau…

A structure-preserving particle discretisation for the Lenard-Bernstein collision operator
Sandra Jeyakumar, Michael Kraus, Matthew Hole +1
Collisions are an important dissipation mechanism in plasmas. In one-dimensional modelling, a commonly used collision operator is the Lenard-Bernstein operator, or its modified ene…
