Abstract: The neoclassical quasilinear theory is extended to the collisional boundary layer and 1 / ν regimes. The theory is for electromagnetic waves with frequencies lower than the bounce frequency of the trapped particles and wavelengths… read more here.

Abstract: The accuracy of quasilinear theory applied to the electron bump-on-tail instability, a classic model problem, is explored with conservative high-order discontinuous Galerkin methods applied to both the quasilinear equations and to a direct simulation of… read more here.
