论文摘要
在本文中，我们比较了不同的理论方法来描述当粒子间耦合相对较弱时，尤卡瓦流体中集体模式的分散体，以使分散关系的动力学和潜在贡献竞争。与分子dymamic仿真的结果进行了详尽的比较，可以得出结论，在研究的制度中，最佳描述是由广义多余的散装模量和Bohm粒度动力学项的总和提供的。
In this paper we compare different theoretical approaches to describe the dispersion of collective modes in Yukawa fluids when the inter-particle coupling is relatively weak, so that kinetic and potential contributions to the dispersion relation compete. Thorough comparison with the results from molecular dymamics simulation allows us to conclude that in the regime investigated the best description is provided by the sum of the generalized excess bulk modulus and the Bohm-Gross kinetic term.
