Velocity Autocorrelation Function of Magnetized Two-Dimensional   One-Component Plasma
  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.
