光子极化率及其对等离子体波色散的影响

Photon polarizability and its effect on the dispersion of plasma waves

I. Y. Dodin, D. E. Ruiz

摘要:

在等离子体中传播的高频光子表现出线性极化率,其可以影响线性等离子体波的色散。我们提出了一个详细的计算,这种效果的朗缪尔波作为一个特征的例子。给出了两种替代配方。在第一个公式中,我们通过求解电子流体的控制方程来计算朗缪尔波的修正色散,其中光子贡献作为有质动力进入。在第二个公式中,我们提供了一个基于光子极化率的推导。这样就不需要计算有质动力,结果更具有一般性。

英文摘要:

High-frequency photons traveling in plasma exhibit a linear polarizability that can influence the dispersion of linear plasma waves. We present a detailed calculation of this effect for Langmuir waves as a characteristic example. Two alternative formulations are given. In the first formulation, we calculate the modified dispersion of Langmuir waves by solving the governing equations for the electron fluid, where the photon contribution enters as a ponderomotive force. In the second formulation, we provide a derivation based on the photon polarizability. Then, the calculation of ponderomotive forces is not needed, and the result is more general.
