We consider nonlinear interactions between intense circularly polarized electromagnetic (CPEM) waves and electron plasma oscillations (EPOs) in a dense quantum plasma, taking into account the electron density response in the presence of the relativistic ponderomotive force and mass increase in the CPEM wave fields. The dynamics of the CPEM waves and EPOs is governed by the two coupled nonlinear Schrödinger equations and Poisson's equation. The nonlinear equations admit the modulational instability of an intense CPEM pump wave against EPOs, leading to the formation and trapping of localized CPEM wave pipes in the electron density hole that is associated with a positive potential distribution in our dense plasma. The relevance of our investigation to the next generation intense laser-solid density plasma interaction experiments is discussed.
我们考虑了致密量子等离子体中强圆偏振电磁（CPEM）波与电子等离子体振荡（EPOs）之间的非线性相互作用，其中考虑了相对论性有质动力存在时的电子密度响应以及CPEM波场中的质量增加。CPEM波和EPOs的动力学由两个耦合的非线性薛定谔方程和泊松方程支配。这些非线性方程允许强CPEM泵浦波对EPOs产生调制不稳定性，从而导致在与我们致密等离子体中的正电势分布相关的电子密度空穴中形成并捕获局域化的CPEM波导管。讨论了我们的研究与下一代强激光 - 固体密度等离子体相互作用实验的相关性。
