TUR - Mathematical aspects of turbulence: where do we stand?

Authors: Jack Coughlin (University of Washington), Jingwei Hu (University of Washington) The Vlasov-Maxwell-Landau system can provide a high fidelity reproduction of plasma physics, but only at great computational cost. Recently, the dynamical low-rank method has been applied to kinetic simulation of plasmas, with promising results. The existence of low-rank structure in asymptotic limits of collisional kinetic equations is further motivation for its application to this class of systems. We introduce the dynamical low-rank method and the robust projector-splitting integrator. We then discuss an asymptotic-preserving discretization for the high-field limit of the Vlasov-Ampere system, a simplification of the Vlasov-Maxwell system
