Equation of state of spin-polarized nuclear matter in the relativistic Hartree-Fock method
Toi Tachibana, Kouichi Hagino, Kenichi Yoshida +1
We calculate the equation of state (EOS) of spin-polarized nuclear matter in the relativistic Hartree-Fock method. To this end, we employ the relativistic point-coupling model, wit…
Ferromagnetic instabilities in quarkyonic matter
Bikai Gao, Kenichi Yoshida
We investigate the magnetic properties of quarkyonic matter, which naturally bridges nuclear and quark matter at intermediate densities relevant to neutron star cores. We extend th…
Correlations of -values with symmetry energy and effective mass studied within Skyrme energy--density functionals
Futoshi Minato, Yifei Niu, Kenichi Yoshida
The -decay half-lives of nuclei are sensitive to the values of . For accurate theoretical predictions, it is essential to develop an effective interaction or an energy de…
Exact-exchange relativistic density functional theory in three-dimensional coordinate space
Qiang Zhao, Zhengxue Ren, Pengwei Zhao +1
The exact-exchange relativistic density functional theory (Ex-RDFT) of atomic nuclei has been solved in three-dimensional lattice space for the first time. The exchange energy is t…
Proton-neutron pair correlations in neutron-rich nuclei
Kenichi Yoshida
[Background] Nuclear pairing is a well-established many-body correlation, particularly among like particles in a spin-singlet state. However, the strength of spin-triplet proton-ne…
