Energy oscillations observed in the MD simulations of plasmas

The molecular dynamics (MD) simulation is a specialized tool which can capture the effects of particle-particle interactions in a many-body system. A GPU-accelerated MD code has been developed to deal with the Coulomb interactions of particle-particle pairs. This research reports the oscillatory behavior of the temperature and potential energy observed in the MD simulations of plasmas. The numerical experiments are performed to investigate the frequency dependence on the plasma coupling parameter and particle mass.
