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.

In this work we study the thermodynamic properties of an asymmetric system with arbitrary proton fraction, [Formula: see text]. We employ a Skyrme model in which surface and Coulomb effects are included phenomenologically to treat finite nuclei. We analyze the chemical and mechanical instabilities as a function of the asymmetry parameter. The coexistence surfaces (binodals) for different temperatures are constructed. We present applications to a set of finite nuclei, taking their critical parameters into account.

The recent progress of the relativistic many-body approach by the group at Peking University will be reviewed. In particular, the adiabatic and configuration-fixed constrained triaxial RMF approaches, triaxial RMF approach with time-odd components, a Shell-model-Like APproach (SLAP), a Reflection ASymmetric RMF (RAS-RMF) approach, and a new relativistic Hartree-Fock (RHF) approach with density-dependent σ, ω, ρ and π meson-nucleon couplings for finite nuclei and nuclear matter, will be highlighted.
