Density dependence of the nuclear energy-density functional
Papakonstantinou, Panagiota,Park, Tae-Sun,Lim, Yeunhwan,Hyun, Chang Ho American Physical Society 2018 Physical Review C Vol.97 No.1
<P>Conclusions: Having been already determined for homogeneous matter, a functional of the present form can be mapped onto extended Skyrme-type functionals in a straightforward manner, as we outline here, for applications to finite nuclei. At the same time, the statistical analysis can be extended to higher orders and for different microscopic (ab initio) calculations with sufficient pseudodata points and for polarized matter.</P>
Skyrme-Type Nuclear Force for the KIDS Energy Density Functional
길하나,오용석,현창호,Panagiota PAPAKONSTANTINOU 한국물리학회 2017 New Physics: Sae Mulli Vol.67 No.4
We construct an effective nucleon-nucleon potential for describing the interactions of nucleons in nuclei or in nuclear matter. Starting from the KIDS (Korea: IBS-Daegu-Sungkyunkwan) nuclear energy density functional systematically expanded in powers of the Fermi momentum, or cubic root of the density, we fit the parameters of the model to a well-known theoretical equation of state of nuclear matter and the empirical data for symmetric nuclear matter. We then determine an effective potential that reproduces the given energy density functional in the mean-field approximation. The potential thus obtained is applied to calculate the binding energies and the sizes of the closed-shell nuclei, namely, $^{16}$O, $^{28}$O, $^{40}$Ca, and $^{60}$Ca. This process introduces one additional parameter, and calculations were made by varying the value of this parameter. We found that the model reasonably reproduced the observed data for the closed-shell nuclei to very good accuracy. Predictions on unobserved physical quantities are presented as well.
Shape Coexistence in Isotopes from Oxygen to Calcium
In Eun Jin,Kim Youngman,Papakonstantinou Panagiota,Hong Seung-Woo 한국물리학회 2020 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.77 No.11
We study structural features in the ground states of isotopes from O to Ca in the framework of the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc) with the PC-PK1 density functional. Focusing on nuclear shapes, we survey our results for candidates of shape coexistence and propose potential candidate isotopes. We expect that some of the proposed candidates could be accessible by RAON in its early stage.
