TL;DR: In this article, the M.I.T. bag model of hadrons was used to show that a neutron matter-quark phase transition is energetically favorable at densities around ten to twenty times nuclear matter density.

TL;DR: In this paper, the Lagrangian density in the relativistic mean field (RMF) theory has been modeled in a microscopic way, which is essential to unify the description of nuclei from light to heavy regions with one effective interaction.
Abstract: New parameter sets for the Lagrangian density in the relativistic mean field (RMF) theory, PK1 with nonlinear sigma- and omega-meson self-coupling, PK1R with nonlinear sigma-, omega-, and rho-meson self-coupling, and PKDD with the density-dependent meson-nucleon coupling are proposed. They are able to provide an excellent description not only for the properties of nuclear matter but also for the nuclei in and far from the valley of beta stability. For the first time in the parametrization of the RMF Lagrangian density, the center-of-mass correction is treated by a microscopic way, which is essential to unify the description of nuclei from light to heavy regions with one effective interaction.

TL;DR: In this article, the effects of very strong magnetic fields on the equation of state (EOS) in multicomponent, interacting matter by developing a covariant description for the inclusion of the anomalous magnetic moments of nucleons was studied.
Abstract: We study the effects of very strong magnetic fields on the equation of state (EOS) in multicomponent, interacting matter by developing a covariant description for the inclusion of the anomalous magnetic moments of nucleons For the description of neutron star matter, we employ a field-theoretical approach, which permits the study of several models that differ in their behavior at high density Effects of Landau quantization in ultrastrong magnetic fields (B > 1014 G) lead to a reduction in the electron chemical potential and a substantial increase in the proton fraction We find the generic result for B > 1018 G that the softening of the EOS caused by Landau quantization is overwhelmed by stiffening due to the incorporation of the anomalous magnetic moments of the nucleons In addition, the neutrons become completely spin polarized The inclusion of ultrastrong magnetic fields leads to a dramatic increase in the proton fraction, with consequences for the direct Urca process and neutron star cooling The magnetization of the matter never appears to become very large, as the value of |H/B| never deviates from unity by more than a few percent Our findings have implications for the structure of neutron stars in the presence of large frozen-in magnetic fields
