摘要：
采用分子动力学方法研究了二维单组分等离子体（OCP）的速度自相关函数（VAF）。的VAF表现出明确的振荡，其频率是独立的无量纲耦合参数γ。然而，均匀的垂直外部磁场的存在增加了第一峰的高度。分子动力学计算机模拟结果的二维OCP在一个垂直的磁场的等离子体参数的函数。我们的模拟结果清楚地表明，在高温下，磁场影响的VAF在很大程度上。
英文摘要：
The velocity autocorrelation function (VAF) for a two-dimensional one-component plasma (OCP) is investigated by employing molecular dynamics techniques. The VAF exhibits well defined oscillations whose frequency is independent of the dimensionless coupling parameter Gamma. However, the presence of a uniform perpendicular external magnetic field increases the height of the first peak. Molecular dynamics computer simulation results are presented for a two-dimensional OCP in a perpendicular magnetic field as a function of the Plasma parameter. Our simulation results clearly indicate that at high temperature, the magnetic field affects the VAF in a substantial way.
