Geometrical optics in phase space
I. Y. Dodin, N. A. Lopez, Tingjing Xing +2
Geometrical optics (GO) is widely used for reduced modeling of waves in plasmas but fails near reflection points, where it predicts a spurious singularity of the wave amplitude. We…
Counting topological interface modes using simplicial characteristic classes
N. Bohlsen, I. Y. Dodin, H. Qin
A computational approach for predicting the number of topological interface modes (TIMs) in hermitian systems using the spectral flow - monopole (SFM) correspondence is presented.…
Quasilinear theory for inhomogeneous plasma
I. Y. Dodin
This paper presents quasilinear theory (QLT) for classical plasma interacting with inhomogeneous turbulence. The particle Hamiltonian is kept general; for example, relativistic, el…
Restoring geometrical optics near caustics using sequenced metaplectic transforms
N. A. Lopez, I. Y. Dodin
Geometrical optics (GO) is often used to model wave propagation in weakly inhomogeneous media and quantum-particle motion in the semiclassical limit. However, GO predicts spurious…
Kinetic simulations of X-B and O-X-B mode conversion and its deterioration at high input power
A. V. Arefiev, I. Y. Dodin, A. Köhn +4
Spherical tokamak plasmas are typically overdense and thus inaccessible to externally-injected microwaves in the electron cyclotron range. The electrostatic electron Bernstein wave…
Kinetic simulations of X-B and O-X-B mode conversion
A. V. Arefiev, E. J. Du Toit, A. Köhn +3
We have performed fully-kinetic simulations of X-B and O-X-B mode conversion in one and two dimensional setups using the PIC code EPOCH. We have recovered the linear dispersion rel…
