We study the properties of neutron stars adopting relativistic equations of state of neutron star matter, calculated in the framework of the relativistic Brueckner–Hartree–Fock approximation for electrically charge neutral neutron star matter in beta–equilibrium. For higher densities more baryons (hyperons etc.) are included by means of the relativistic Hartree– or Hartree–Fock approximation. T...

It is a well known fact that mean-field approximation to the nuclear many-body problem introduces center-of-mass (CM) spurious components in the solutions. In particular, Hartree-Fock self-consistent mean-fields obtained using realistic forces in a non-relativistic approach have been considered, and the corresponding CM corrections have been calculated for the energy [1, 2] as well as for other...

The structure of in nite nuclear matter is studied with two of the Zimanyi Moszkowski (ZM) models in the framework of a relativistic approximation which takes into account Hartree terms and beyond and is compared with the results which come out of the relativistic Hartree Fock approach in the linear Walecka model. The simple treatment applied to these models can be used in substitution to the m...

The structure of infinite nuclear matter is studied with two of the Zimanyi Moszkowski (ZM) models in the framework of a relativistic approximation which takes into account Hartree terms and beyond and is compared with the results which come out of the relativistic Hartree Fock approach in the linear Walecka model. The simple treatment applied to these models can be used in substitution to the ...

We present static electric dipole polarizabilities αd(Z,N) from numerical nonrelativistic restricted Hartree-Fock (RHF) finite-field calculations for high-spin open-shell S states (L = 0) of atoms and isoelectronic ions with N ≤ 55 electrons. All these S states result from one or more half-filled shells. For eight isoelectronic sequences, those with N = 3, 7, 11, 15, 23, 29, 33 or 41 electrons ...

Hartree-Fock calculations with the SKX Skyrme interaction are carried out to obtain a-decay Q values for deformed nuclei above Pb assuming axial symmetry. The results for even-even nuclei are compared with the experiment and with the previous calculations. Predictions are made for a-decay Q values and half-lives of even-even superheavy nuclei. The results are also compared for the recently disc...

This article concerns the time-dependent Hartree-Fock (TDHF) approximation of single-particle dynamics in systems of interacting fermions. We find that the TDHF approximation is accurate when there are sufficiently many particles and the initial manyparticle state is any Gibbs equilibrium state for noninteracting fermions (with Slater determinants as a special example). Assuming a bounded two-p...
