Kinetic simulations and reduced modeling of longitudinal sideband instabilities in nonlinear electron plasma waves
Kinetic Vlasov simulations of onedimensional finite amplitude Electron Plasma Waves are performed in a multiwavelength long system. A systematic study of the most unstable linear sideband mode, in particular its growth rate γ and quasi wavenumber δk, is carried out by scanning the amplitude and wavenumber of the initial wave. Simulation results are successfully compared against numerical and analytical solutions to the reduced model by Kruer et al. [Phys. Rev. Lett. 23, 838 (1969)] for the Trapped Particle Instability (TPI). A model recently suggested by Dodin et al. [Phys. Rev. Lett. 110, 215006 (2013)], which in addition to the TPI accounts for the socalled Negative Mass Instability because of a more detailed representation of the trapped particle dynamics, is also studied and compared with simulations.
