Numerical study of the transverse diffusion coefficient for a one component model of plasma

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 & BOTTOM; in the plane orthogonal to the magnetic field lines. We find that there exists a threshold with respect to the magnetic field strength | B & RARR; |: for weak magnetic field, the diffusion coefficients scale as 1 / | B & RARR; |(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 autocorrelation.

Automated summary

This paper discusses the results of molecular dynamics simulations for a magnetized one component plasma, with the aim of estimating the diffusion coefficient in the plane perpendicular to the magnetic field. The authors find that there is a threshold in terms of the magnetic field strength: for weak fields, the diffusion coefficients scale as 1/magnetic field strength squared, while a slower decay is observed at high field strength. The relationship between this transition and the mixing properties of the microscopic dynamics is investigated by analyzing the behavior of velocity autocorrelation.
