Rmf Model

Effects of the ω meson self coupling (OMSC) on the thermal properties of asymmetric nuclear matter (ANM) are studied within the framework of relativistic mean field (RMF) model that includes contributions of all possible mixed interactions among meson fields involved up to quartic order. In particular, we study the mechanical and chemical instabilities (spinodal), as well as the liquid-gas phase transition (binodal) at finite temperature. It is found that the onset of spinodal instabilities and the binodal curve are only marginally affected by variation of the OMSC parameter, whereas the binodal curve shows a strong correlation to the symmetry energy. Comparison with other ERMF parameter sets is also performed.

A study of the equation of state (EOS) for cold asymmetric nuclear matter and beta-stable matter using effective interactions, of zero range (Skyrme type) and finite range type (D1-Gogny), is performed in the Hartree-Fock approach. The results are systematically compared with recent microscopic calculations. Two parametrizations of the energy of asymmetric nuclear matter in terms of the asymmetry parameter are tested in the case of effective interactions. While all forces agree rather well for nuclear matter, some discrepancies appear for neutron matter revealing the different spin-isospin contents of the interactions.
