We derive an equation of state for asymmetric nuclear matter at finite temperature, using the Skyrme effective nucleon-nucleon interaction and a mean field approach based on a real-time finite temperature Green’s function method with a normal pair cutoff approximation. With the temperature held constant, it is found that nuclear matter can exist only in the gaseous phase when its neutron excess coefficient a has surpassed a certain critical value αc. We have calculated αc for a number of different Skyrme effective interactions. Phase diagrams involving a are obtained, and a low-density equation for the phase boundary is derived.

The equation of state of the asymmetric nuclear matter is calculated with the Gogny D1 effective density-dependent nucleon-nucleon interaction and the Coulomb interaction in the framework of the finite-temperature HF method with the rearrangement term. The dependence of the thermodynamical properties such as the critical temperature of the liquid-gas phase transition, the chemical potential, the compression modulus and the entropy on the Coulomb interaction in nuclear matter is treated by using a shielded two-body Coulomb potential and this method has been found to be a reasonable and effective approach.

A Variational Monte Carlo method (VMC) is described for the evaluation of the ground state properties of nuclear matter. Equilibrium properties of symmetric nuclear matter and neutron matter are calculated by the described VMC method. The Urbana ν14 potential is used for the nucleon–nucleon interactions in the calculations. Three- and more-body interactions are included as a density dependent potential term. Total, kinetic and potential energies per particle are obtained for nuclear and neutron matter. Pressure values of nuclear and neutron matter are also calculated at various densities. The binding energy of nuclear matter is found to be -16.06 MeV at a saturation density of 0.16 fm -3. The results obtained are in good agreement with those obtained by various authors with different potentials and techniques.
