Positivity-preserving semi-Lagrangian discontinuous Galerkin methods for multi-species Vlasov-Amp\`ere models of plasma
We develop a high-order and positivity-preserving kinetic solver for the multi-species Vlasov-Amp\`ere system that is built within a semi-Lagrangian discontinuous Galerkin (SLDG) framework. The method is designed for efficiency and accuracy across a broad range of conditions, including stiff, multi-scale regimes with s...
