绝热波粒相互作用的再认识

Adiabatic Wave-Particle Interaction Revisited

R. L. Dewar, J. C. -C. Yap

摘要:

在本文中,我们计算和可视化的动态系综的电子捕获在一个静电波的振幅缓慢增加,说明,尽管无序的粒子在角度的捕获过渡过程中,因为他们通过接近X点,仍然有一个绝热不变的绝大多数粒子,允许预测的长时间分布函数。可能的应用这种方法的驱动波的非线性频移最近的工作进行了简要的讨论。

英文摘要:

In this paper we calculate and visualize the dynamics of an ensemble of electrons trapping in an electrostatic wave of slowly increasing amplitude, illustrating that, despite disordering of particles in angle during the trapping transition as they pass close to X-points, there is still an adiabatic invariant for the great majority of particles that allows the long-time distribution function to be predicted. Possible application of this approach to recent work on the nonlinear frequency shift of a driven wave is briefly discussed.
