Molecular Dynamics Simulations for Neutrino Scattering in Heterogeneous High Dense Media

The dynamics of core-collapse supernovae is sensitive to neutrino scattering. Using molecular dynamics simulations, we calculated ion static structure factors and neutrino mean free paths. We simulated the stellar medium as composed in one case by single ion specie, and in the other by a mixture of ions. For the heterogeneous plasma we used two different models and systematically found the neutrino mean free path is shorter for an ion mixture
