Nuclear incompressibility and fourth moment of the nuclear density in Skyrme functionals
Soonchul Choi, Tae-Sun Park, Panagiota Papakonstantinou
Recent experimental advances could soon allow the accurate extraction of not only the root-mean-square radius but also the fourth radial moment of the nuclear electric charge densi…
Interaction in a Nuclear Density Functional Theory and Hyperon Puzzle of the Neutron Star
Soonchul Choi, Emiko Hiyama, Chang Ho Hyun +1
A Skyrme-type effective potential is determined to describe the interaction between hyperons in nuclear medium. Experimental data of the binding energies of the double- ($ΛΛ…
Effects of neutron-rich nuclei masses on symmetry energy
Seonghyun Kim, Dukjae Jang, Soonchul Choi +2
We explore the impact of neutron-rich nuclei masses on the symmetry energy properties using the mass table evaluated by the deformed relativistic Hartree-Bogoliubov theory in conti…
Odd-even shape staggering and kink structure of charge radii of Hg isotopes by the deformed relativistic Hartree-Bogoliubov theory in continuum
Myeong-Hwan Mun, Seonghyun Kim, W. Y. So +3
We examined the shape staggering of relative charge radii in Hg isotopes, which was first measured in 1977 and recently confirmed using advanced spectroscopy techniqu…
Effects of Many-body Interactions in Hypernuclei with Korea-IBS-Daegu-SKKU Functionals
Soonchul Choi, Emiko Hiyama, Chang Ho Hyun +1
We investigate the properties of hyperon in -hypernuclei using an effective nuclear density functional theory which is based on the low-energy effective field theory. It exp…
Constraints on Nuclear Saturation Properties from Terrestrial Experiments and Astrophysical Observations of Neutron Stars
Soonchul Choi, Tsuyoshi Miyatsu, Myung-Ki Cheoun +1
Taking into account the terrestrial experiments and the recent astrophysical observations of neutron stars and gravitational-wave signals, we impose restrictions on the equation of…
Effects of pairing correlations on the neutron skin thickness and the symmetry energy
Soonchul Choi, Ying Zhang, Myung-Ki Cheoun +3
We investigated effects of pairing correlations on the neutron skin thickness and the symmetry energy of finite nuclei. In this calculation we used Hartree-Fock-Bogoliubov (HFB) me…
Low Energy Effective Hamiltonian for the Fractional Quantum Hall Effect
Myung-Hoon Chung, So-Nam Choi, Jae-Hoon Kwon
A low energy effective Hamiltonian for the fractional quantum Hall effect is obtained by using irreducible representations of the symmetry group. It is found that the model describ…
