Abstract Text:
Collisionless or weakly collisional plasmas are ubiquitous in the universe, necessitating a kinetic description. The Vlasov-Maxwell system of equations describes the evolution of the probability distribution function of the particles subject to self-consistently generated electromagnetic fields. Typically, the Vlasov-Maxwell system is solved in a Lagrangian framework using the particle-in-cell method; however, we focus on the development of a fully kinetic (ions and electrons) Eulerian approach, which is ideal for studying problems requiring low amplitude and high sensitivity, such as energy dissipation in turbulence and magnetic reconnection. In particular, we describe the development and performance of a high-order discontinuous Galerkin simulation code, Gkeyll, in up to 6D phase space. We also present the first fully kinetic Eulerian Vlasov-Maxwell study of turbulence using the Gkeyll simulation code, focusing on the pristine distribution function dynamics that are possible with the Eulerian approach.
