A quasi-neutral electromagnetic hybrid model with drift-kinetic electrons and fully kinetic ions
Guo Meng, Nishant Narechania, Eric Sonnendrücker
In this work, we propose a hybrid model that combines drift-kinetic electrons with fully kinetic ions under the quasi-neutrality assumption, discretized using a geometric particle-…
A dual grid geometric electromagnetic particle in cell method
Katharina Kormann, Eric Sonnendrücker
Geometric particle-in-cell discretizations have been derived based on a discretization of the fields that is conforming with the de Rham structure of the Maxwell's equation and a s…
Variational Framework for Structure-Preserving Electromagnetic Particle-In-Cell Methods
Martin Campos Pinto, Katharina Kormann, Eric Sonnendrücker
In this article we apply a discrete action principle for the Vlasov--Maxwell equations in a structure-preserving particle-field discretization framework. In this framework the fini…
Geometric Particle-in-Cell Simulations of the Vlasov--Maxwell System in Curvilinear Coordinates
Benedikt Perse, Katharina Kormann, Eric Sonnendrücker
Numerical schemes that preserve the structure of the kinetic equations can provide stable simulation results over a long time. An electromagnetic particle-in-cell solver for the Vl…
Energy-conserving time propagation for a geometric particle-in-cell Vlasov--Maxwell solver
Katharina Kormann, Eric Sonnendrücker
This paper discusses energy-conserving time-discretizations for finite element particle-in-cell discretizations of the Vlasov--Maxwell system. A geometric spatially discrete system…
First principles gyrokinetic analysis of electromagnetic plasma instabilities
Natalia Tronko, Alberto Bottino, Cristel Chandre +5
A two-fold analysis of electromagnetic core tokamak instabilities in the framework of the gyrokinetic theory is presented. First principle theoretical foundations of the gyrokineti…
