A structure-preserving multiscale solver for particle-wave interaction in non-uniform magnetized plasmas
Kun Huang, Irene M. Gamba, Chi-Wang Shu
Particle-wave interaction is of fundamental interest in plasma physics, especially in the study of runaway electrons in magnetic confinement fusion. Analogous to the concept of pho…

A structure-preserving local discontinuous Galerkin method for the Fokker-Planck-Landau equation
Kun Huang, Andrés Galindo-Olarte, Rodrigo González-Hernández +1
In this work, we introduce a structure-preserving local discontinuous Galerkin (LDG) method \cite{cockburn1998local} for solving the non-local non-linear Fokker-Planck-Landau (FPL)…

Reconstruction of heat relaxation index in phonon transport equation
Peiyi Chen, Irene M. Gamba, Qin Li +1
For nano-materials, heat conductivity is an ill-defined concept. This classical concept assumes the validity of Fourier's law, which states the heat flux is proportional to tempera…
