Zakharov系统的经典和量子动力学
Classical and quantum kinetics of the Zakharov system
摘要：
导出了量子朗缪尔波与量子离子声波非线性相互作用的动力学理论。该公式允许对Zakharov系统的量子修正进行统计分析。给出了背景随机相位对调制不稳定性的影响。在相干情况下，量子修正的效果是降低生长速率。此外，在经典极限下，由于部分相干性的存在，色散曲线会出现分叉。然而，部分相干性和量子校正的组合效应可能会导致调制不稳定性增长率的增加，与经典的情况相比。这一结果在稠密天体物理等离子体和实验室激光等离子体系统中可能具有重要意义。
英文摘要：
A kinetic theory for quantum Langmuir waves interacting nonlinearly with quantum ion-acoustic waves is derived. The formulation allows for a statistical analysis of the quantum correction to the Zakharov system. The influence of a background random phase on the modulational instability is given. In the coherent case, the effect of the quantum correction is to reduce the growth rate. Moreover, in the classical limit, a bifurcation develops in the dispersion curves due to the presence of partial coherence. However, the combined effect of partial coherence and a quantum correction may give rise to an increased modulational instability growth rate, as compared to the classical case. The results may be of significance in dense astrophysical plasmas and laboratory laser-plasma systems.
