Symmetry interaction and many-body correlations

Abstract

It is shown how many-body correlations involving the symmetry potential naturally arise in the molecular dynamics CoMD-II model. The effect of these correlations on the collision dynamics at the Fermi energies is discussed. Small level of correlations for systems of moderate asymmetry are able to produce large effects also in simple observables like the charge distributions. The comparison with predictions based on Equation Of State static calculations is also discussed.
