The dynamic structure factor and other dynamic characteristics of strongly coupled one-component plasmas have been studied [Yu. V. Arkhipov et al., Phys. Rev. Lett. 119, 045001 (2017)] using the self-consistent version of the method of moments. Within any version of the latter, the system dielectric function satisfies all involved sum rules and other exact relations automatically, and the advantage of this version is that, in addition, the dynamic characteristics (the dynamic structure factor, the dispersion, and decay parameters of the collective modes) are all expressed in terms of the static ones (the static structure factor) without any adjustment to the simulation data. The approach outlined in the aforementioned Letter is justified in detail and applied mainly to the classical Coulomb systems achieving satisfactory agreement with new numerical simulation data. It is shown how the realm of applicability of the method can be extended to partly degenerate and multicomponent systems, even to simple liquids. Some additional theoretical results are presented in the Supplemental Material.

三维强耦合等离子体的动力学特性

研究了强耦合单组分等离子体的动力学结构因子和其他动力学特性[Yu。V.Arkhipov等。，物理 牧师 119，045001（2017）]中使用矩量方法的自洽版本。在后者的任何版本中，系统介电函数均自动满足所有涉及的求和规则和其他精确关系，并且该版本的优点在于，此外，其动态特性（动态结构因子，色散和衰减参数）集合模式）均以静态模式（静态结构因子）表示，无需对模拟数据进行任何调整。上述信中概述的方法已得到详细证明，并且主要应用于经典库仑系统，该系统与新的数值模拟数据取得了令人满意的一致性。它显示了该方法的适用范围如何扩展到部分退化和多​​组分系统，甚至是简单的液体。
