Conservation and breaking of pseudospin symmetry
T. -T. Sun, Z. P. Li, P. Ring
Pseudospin symmetry (PSS) is a relativistic dynamical symmetry connected with the lower component of the Dirac spinor. Here, we investigate the conservation and breaking of PSS in…
Impact of isovector pairing fluctuation on neutrinoless double-beta decay in multi-reference covariant density functional theory
C. R. Ding, X. Zhang, J. M. Yao +2
We extend the multi-reference covariant density functional theory (MR-CDFT) by including fluctuations in quadrupole deformations and average isovector pairing gaps simultaneously f…
Neutron-proton effective mass splitting in neutron-rich matter
Sibo Wang, Hui Tong, Qiang Zhao +3
Nucleon effective masses in neutron-rich matter are studied with the relativistic Brueckner-Hartree-Fock (RBHF) theory in the full Dirac space. The neutron and proton effective mas…
The optimized point-coupling interaction for the relativistic energy density functional of Hartree-Bogoliubov approach quantifying the nuclear bulk properties
Zi Xin Liu, Yi Hua Lam, Ning Lu +1
We propose a newly optimized nonlinear point-coupling parameterized interaction, PC-L3R, for the relativistic Hartree-Bogoliubov framework with a further optimized separable pairin…
Asymmetric Nuclear Matter and Neutron Star Properties in Relativistic ab initio Theory in the Full Dirac Space
Sibo Wang, Hui Tong, Qiang Zhao +3
The long-standing controversy about the isospin dependence of the effective Dirac mass in ab initio calculations of asymmetric nuclear matter is clarified by solving the relativist…
Global performance of covariant density functional theory in description of charge radii and related indicators
A. V. Afanasjev, U. C. Perera, P. Ring
A short review of existing efforts to understand charge radii and related indicators on a global scale within the covariant density functional theory (CDFT) is presented. Using maj…
