强耦合等离子体中关联的形成

Formation of correlations in strongly coupled plasmas

K. Morawetz, V. Špička, P. Lipavský

摘要:

从量子动力学方程出发,研究了等离子体中二元关联的形成。结果表明,这种形成是远远快于耗散由于碰撞。在热(稠密)等离子体中,相关性形成在等离子体频率(费米能)的倒数尺度上。我们推导出分析公式的时间依赖性的势能的相关性的程度进行测量。讨论了屏蔽的动态形成,并与静态屏蔽结果进行了比较。与分子动力学模拟的比较。

英文摘要:

The formation of binary correlations in plasma is studied from the quantum kinetic equation. It is shown that this formation is much faster than dissipation due to collisions. In a hot (dense) plasma the correlations are formed on the scale of inverse plasma frequency (Fermi energy). We derive analytical formulae for the time dependency of the potential energy which measures the extent of correlations. We discuss the dynamical formation of screening and compare with the statical screened result. Comparisons are made with molecular dynamic simulations.
