In this work, we propose a metamodeling technique to nuclear matter on the basis of a
relativistic density functional with density-dependent couplings. Identical density …

We construct new effective interactions using the relativistic mean-field models with the
isoscalar-and isovector-meson mixing, σ 2 δ 2 and ω μ ω μ ρ ν ρ ν. Taking into account the …

We study the effect of the isovector-scalar meson a 0 (980) on the properties of nuclear
matter and the neutron star (NS) matter by constructing a parity doublet model with including …

The effects of the isovector scalar δ-meson field on the properties of finite nuclei, infinite
nuclear matter, and neutron stars are investigated within a relativistic mean field (RMF) …

A recent assessment of the central compact object in the supernova remnant HESS J 1731-
347 [Nat. Astron. 6, 1444 (2022) 2397-3366 10.1038/s41550-022-01800-1] reveals its …

The central speed of sound (SS) measures the stiffness of the equation of state (EOS) of
superdense neutron star (NS) matter. Its variations with density and radial coordinate in NSs …

The recent pioneering campaigns conducted by the Lead Radius Experiment (PREX) and
the Calcium Radius Experiment (CREX) Collaborations have uncovered major deficiencies …

It has been found that the topology effect and the possible emergent hidden scale and
hidden local flavor symmetries at high density reveal a novel structure of compact star …

We construct the equation of state (EOS) of QCD based on the finite chemical potential
information from the functional QCD approaches with the results at zero chemical potential …

In this review, we summarize recent studies on nuclear matter and finite nuclei based on
parity doublet models. We first construct a parity doublet model (PDM), which includes the …
