零温中性等离子体振荡

Neutral Plasma Oscillations at Zero Temperature

S. D. Bergeson, R. L. Spencer

摘要:

本文用冷等离子体理论计算了超冷中性等离子体对外加射频场的响应。系统的自由振荡具有连续谱和相应的阻尼准模。我们表明,这种准模式占主导地位的驱动响应。我们使用这个模型来模拟等离子体振荡在一个不断扩大的超冷中性等离子体,提供洞察的假设用于解释实验数据[物理评论快报。85,318(2000)]。

英文摘要:

We use cold plasma theory to calculate the response of an ultracold neutral plasma to an applied rf field. The free oscillation of the system has a continuous spectrum and an associated damped quasimode. We show that this quasimode dominates the driven response. We use this model to simulate plasma oscillations in an expanding ultracold neutral plasma, providing insights into the assumptions used to interpret experimental data [Phys. Rev. Lett. 85, 318 (2000)].
