论文摘要
在本文中，我们讨论了磁化一个组件等离子体的某些分子动力学模拟的结果，该结果旨在估计平面正交与磁场线的平面正交中的扩散系数$ d _ {\ perp} $。我们发现，相对于磁场强度$ | \ vec b | $：对于弱磁场，扩散系数尺度为$ 1/| \ vec b |^2 $，而较慢的衰变则以高磁场强度出现。通过查看速度自动相关性的行为来研究这种过渡与微观动力学的不同混合特性的关系。
In this paper we discuss the results of some Molecular Dynamics simulations of a magnetized One Component Plasma, targeted to estimate the diffusion coefficient $D_{\perp}$ in the plane orthogonal to the magnetic field lines. We find that there exists a threshold with respect to the magnetic field strength $|\vec B|$: for weak magnetic field the diffusion coefficients scales as $1/|\vec B|^2$, while a slower decay appears at high field strength. The relation of this transition with the different mixing properties of the microscopic dynamics is investigated by looking at the behavior of the velocity auto correlation.
