Lukas Einkemmer, Jingwei Hu, Yubo Wang

Abstract: Highlights•First asymptotic preserving dynamical low-rank scheme that is explicitly implementable.•Second order both in the fully kinetic and in the asymptotic regime.•Significant reduction in the computational effort compared to full grid methods.•A range of realistic numerical simulation demonstrates the efficiency of our approach.
