论文摘要

我们使用Landau-Lifshitz辐射反应扩展的相对论Vlasov方程研究了静电等离子体波的演变,这是由于单个颗粒Larmor辐射的发射而考虑的后反应。特别是,Langmuir波阻尼是根据波数,初始温度和初始电场振幅的函数计算的。此外,背景分布函数在此过程中会失去能量,我们计算出最初温度和初始波幅度的函数的冷却速率。最后,我们研究了波阻尼和背景冷却的相对大小如何随初始参数而变化。特别是,发现与背景冷却相关的能量损失的相对贡献随着初始波幅度而缓慢降低。

We study the evolution of electrostatic plasma waves, using the relativistic Vlasov equation extended by the Landau-Lifshitz radiation reaction, accounting for the back-reaction due to the emission of single particle Larmor radiation. In particular, the Langmuir wave damping is calculated as a function of wavenumber, initial temperature, and initial electric field amplitude. Moreover, the background distribution function loses energy in the process, and we calculate the cooling rate as a function of initial temperature and initial wave amplitude. Finally, we investigate how the relative magnitude of wave damping and background cooling varies with the initial parameters. In particular, it is found that the relative contribution to the energy loss associated with background cooling decreases slowly with the initial wave amplitude.
