Symmetry interaction and many-body correlations

TL;DR

This paper explores how many-body correlations involving symmetry potential influence collision dynamics at Fermi energies, revealing significant effects on observables like charge distributions, and compares dynamic and static equation of state predictions.

Contribution

It demonstrates the natural emergence of many-body symmetry correlations in the CoMD-II model and their impact on collision outcomes at Fermi energies.

Findings

Correlations significantly affect charge distributions.

Dynamic correlations differ from static EOS predictions.

Small asymmetry correlations can produce large observable effects.

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.
