液体中波的传播与Landau型阻尼

Wave Propagation And Landau-Type Damping In Liquids

Vincenzo Molinari, Domiziano Mostacci

摘要:

分子间力通过修改后的Lennard-Jones势建模,引入最小距离的方法,和分子间相互作用的效果占与自洽场的Vlasov型。一个Vlasov方程,然后写入和用于调查在液体中的扰动的传播。色散关系得到的阻尼,类似于什么是已知的等离子体中的“朗道阻尼”的效果,被发现发生。

英文摘要:

Intermolecular forces are modeled by means of a modified Lennard-Jones potential, introducing a distance of minimum approach, and the effect of intermolecular interactions is accounted for with a self consistent field of the Vlasov type. A Vlasov equation is then written and used to investigate the propagation of perturbations in a liquid. A dispersion relation is obtained and an effect of damping, analogous to what is known in plasmas as "Landau damping", is found to take place.
