Description
Summary:In this work, the W. Ebeling potential including the quantum effects and Monte Carlo numerical simulation have been briefly described. The limits of this potential between the classical and quantum effects were calculated. The electric microfield distribution functions in quantum plasma were calculated, mainly, using Monte Carlo (MC) and molecular dynamics (MD) simulations. To carry out this task, W. Ebeling potential, which includes quantum effects at small interspaces between various components of the plasma (ions and electrons), has been considered. All interactions (ion–ion, ion–electron) were taken into account during the calculation, which is the same idea that Hooper dealt with this issue, but considering the Coulomb or Debye potential. The results were compared with other similar works: the best classical model APEX and Sadykova with quantum effect. Most of our results have showed a near perfect agreement. Some behaviours of these functions have been deduced for different coupling parameters, quantification degrees and plasma types.
