From Brueckner Approach to Skyrme-type Energy Density Functional
A Skyrme-like effective interaction is built up from the equation of state of nuclear matter. The latter is calculated in the framework of the Brueckner-Hartree-Fock approximation with two and three body forces. A complete Skyrme parametrization requires a fit of the neutron and proton effective masses and also the Landau parameters. The new parametrization is probed on the properties of a set ...
متن کاملNeutron drops and Skyrme energy-density functionals.
The J =0 ground state of a drop of 8 neutrons and the lowest 1/2 and 3/2 states of 7-neutron drops, all in an external well, are computed accurately with variational and Green's function Monte Carlo methods for a Hamiltonian containing the Argonne v18 two-nucleon and Urbana IX three-nucleon potentials. These states are also calculated using Skyrme-type energy-density functionals. Commonly used ...
متن کاملCasimir Energy in the Skyrme Model
The so called Casimir energy embodies the O((Nc) ) contribution to the skyrmion mass according to the semi-classical expansion theory of solitons. We claim that this contribution can be accurately estimated despite the fact that some of the counterterms, provided in principle by chiral perturbation theory, are not known in practice. Using ζ function techniques we show that Ecas = Ecas(μ) + Ect(...

متن کاملSpectroscopic properties of nuclear skyrme energy density functionals.
We address the question of how to improve the agreement between theoretical nuclear single-particle energies (SPEs) and observations. Empirically, in doubly magic nuclei, the SPEs can be deduced from spectroscopic properties of odd nuclei that have one more or one less neutron or proton. Theoretically, bare SPEs, before being confronted with observations, must be corrected for the effects of th...
