Energy-momentum-conserving stochastic differential equations and algorithms for nonlinear Landau-Fokker-Planck equation
Yichen Fu, Justin R. Angus, Hong Qin +1
Coulomb collision is a fundamental diffusion process in plasmas that can be described by the Landau-Fokker-Planck (LFP) equation or the stochastic differential equation (SDE). Whil…

Nonlinear solution of classical three-wave interaction via finite dimensional quantum model
Michael May, Hong Qin
The quantum three-wave interaction, the lowest order nonlinear interaction in plasma physics, describes energy-momentum transfer between three resonant waves in the quantum regime.…

Topological modes and spectral flows in inhomogeneous PT-symmetric continuous media
Yichen Fu, Hong Qin
In classical Hermitian continuous media, the spectral-flow index of topological modes is linked to the bulk topology via index theorem. However, the interface between two bulks is…
