MD simulation study for nuclear matter

Properties of nuclear matter below the nuclear saturation density is analyz ed by molecular dynamics (MD) simulations with the periodic boundary condit ion. The equation of state at these densities is softened by the formation of cluster(s) with internal density nearly equal to the saturation density. The structure of nuclear matter shows some exotic shapes with variation of the density. Furthermore, it is found that the symmetry parameter a(sym)(p ) is not a linear function of density at low density region.
