Effective computer simulation of strongly coupled Coulomb fluids

The problem of accurately accounting for long ranged Coulomb forces within periodic boundaries in Monte Carlo and molecular dynamics computer simulation of strongly coupled Coulomb systems is considered. Periodicity artefacts characteristic of the conventional Ewald summation procedure are eliminated by angular averaging of Ewald sums over all orientations of the main cell. This approach provides an effective analytical electrostatic interaction potential and allows fast and accurate simulations of strongly coupled Coulomb fluids even on a modem PC. The effectiveness and accuracy of the method is illustrated on simple non-ideal plasma models.
