P. K. Shukla, S. Ali, L. Stenflo, M. Marklund

摘要:

考虑了量子磁等离子体中静电上杂化波、离子回旋波、下杂化波和阿尔芬波的非线性相互作用。为此,量子流体动力学方程用于推导非线性耦合UH,IC,LH和阿尔芬波的控制方程。然后对方程进行傅立叶分析,得到非线性色散关系,该关系承认量子尺度下UH波的衰减和调制不稳定性。给出了不稳定性的增长率。它们可以在我们的工作在实验室和天体物理环境中的诊断应用中发挥作用。

英文摘要:

Nonlinear interactions involving electrostatic upper-hybrid (UH), ion-cyclotron (IC), lower-hybrid (LH), and Alfven waves in quantum magnetoplasmas are considered. For this purpose, the quantum hydrodynamical equations are used to derive the governing equations for nonlinearly coupled UH, IC, LH, and Alfven waves. The equations are then Fourier analyzed to obtain nonlinear dispersion relations, which admit both decay and modulational instabilities of the UH waves at quantum scales. The growth rates of the instabilities are presented. They can be useful in applications of our work to diagnostics in laboratory and astrophysical settings.
