“…1 is shown the EOS of symmetric nuclear matter predicted using the BHF approaches [6,8], the variational method [13], and the relativistic DBHF theory [14]. Within the two nonrelativistic frameworks (i.e., the nonrelativistic BHF and variational approaches), the predicted saturation densities by adopting purely two-body interactions are shown to be much higher than the empirical one.…”

“…As soon as the G matrix is obtained, one can calculate the properties of nuclear matter. We adopt the AV 18 two-body interaction or the Bonn potential plus a microscopic TBF [6][7][8] as our realistic NN interaction. The adopted TBF model is based on the meson exchange current approach [12] and its parameters are determined self-consistently by the corresponding two-body force within the one-boson-exchange potential model and there is no adjustable parameters.…”

“…First, the calculation of the effect of ground state correlations has been extended to asymmetric nuclear matter [5]. Second, microscopic three-body forces (TBF) have been included in the BHF scheme [6][7][8] and the calculation of the TBF-induced rearrangement contribution to the s.p. properties has been realized in Brueckner theory [9,10].…”

We give a review of our investigation on the single-particle properties and the equation of state (EOS) of asymmetric nuclear matter within the framework of the Brueckner theory extended to include a microscopic three-body force. Especially, we discuss the three-body force effect. It is shown the three-body force is crucial for reproducing the empirical saturation properties within nonrelativistic microscopic frameworks and may enhance strongly the stiffness of symmetry energy at high densities. As for the single particle properties, the three-body force turns out to induces a strongly repulsive and momentum-dependent rearrangement contribution to the single particle potential and enhances significantly the depletion of nuclear Fermi sea, at high densities.

The equation of state (EoS) of hot and dense matter is a fundamental input to describe static and dynamical properties of neutron stars, core-collapse supernovae and binary compact-star mergers. We review the current status of the EoS for compact objects, that have been studied with both ab-initio many-body approaches and phenomenological models. We limit ourselves to the description of EoSs with purely nucleonic degrees of freedom, disregarding the appearance of strange baryonic matter and/or quark matter. We compare the theoretical predictions with different data coming from both nuclear physics experiments and astrophysical observations. Combining the complementary information thus obtained greatly enriches our insight into the dense nuclear matter properties. Current challenges in the description of the EoS are also discussed, mainly focusing on the model dependence of the constraints extracted from either experimental or observational data, the lack of a consistent and rigorous many-body treatment at zero and finite temperature of the matter encountered in compact stars (e.g. problem of cluster formation and extension of the EoS to very high temperatures), the role of nucleonic three-body forces, and the dependence of the direct URCA processes on the EoS.
