The nuclear symmetry energy is defined by the second derivative of the energy per nucleon with respect to the proton-neutron asymmetry, and is sometimes approximated by the energy difference between the neutron matter and the symmetric matter. Accuracy of this approximation is assessed analytically and numerically, within the Hartree-Fock theory using effective interactions. By decomposing the nuclear-matter energy, the relative error of each term is expressed analytically; it is constant or is…

Crust-core interface and bulk neutron star properties
The nuclear symmetry energy plays an important role in the description of the properties of finite nuclei as well as neutron stars. Especially, for low values of baryon density, the accurate
Quantifying the uncertainties on spinodal instability for stellar matter through meta-modeling
The influence of the uncertainties of the equation of state empirical parameters on the neutron stars crust-core phase transition is explored within a meta-modeling approach, in which the energy per
Equation of state for dense nucleonic matter from metamodeling. I. Foundational aspects
A metamodeling for the nucleonic equation of state (EOS), inspired from a Taylor expansion around the saturation density of symmetric nuclear matter, is proposed and parameterized in terms of the
Properties of exotic nuclei and their linkage to the nucleonic interaction
The structure of exotic nuclei sheds new light on the linkage of the nuclear structure to the nucleonic interaction. The self-consistent mean-field (SCMF) theories are useful to investigate this


Divergence of the isospin-asymmetry expansion of the nuclear equation of state in many-body perturbation theory
The isospin-asymmetry dependence of the nuclear matter equation of state obtained from microscopic chiral two- and three-body interactions in second-order many-body perturbation theory is examined in
Hartree-Fock approach to nuclear matter and finite nuclei with M3Y-type nucleon-nucleon interactions
By introducing a density-dependent contact term, M3Y-type interactions applicable to the Hartree-Fock calculations are developed. In order to view basic characters of the interactions, we carry out
Asymmetric nuclear matter equation of state.
The present calculations of the incompressibility predict a strong softening of the equation of state going from symmetric to asymmetric nuclear matter.
Microscopic calculations and energy expansions for neutron-rich matter
We investigate asymmetric nuclear matter with two- and three-nucleon interactions based on chiral effective field theory, where three-body forces are fit only to light nuclei. Focusing on
Semi-realistic nucleon-nucleon interactions with improved neutron-matter properties
New parameter-sets of the semi-realistic nucleon-nucleon interaction are developed, by modifying the M3Y interaction but maintaining the tensor channels and the longest-range central channels. The

Abstract:Brueckner calculations including a microscopic three-body force have been extended to isospin-asymmetric nuclear matter. The effects of the three-body force on the equation of state and on
First Gogny-Hartree-Fock-Bogoliubov nuclear mass model.
The first Gogny-Hartree-Fock-Bogoliubov (HFB) model is presented, which reproduces nuclear masses with an accuracy comparable with the best mass formulas and is shown to predict nuclear and neutron matter properties in agreement with microscopic calculations based on realistic two- and three-body forces.
