Can the PREX-2 and CREX results be understood by relativistic mean-field models with the astrophysical constraints?
Tsuyoshi Miyatsu, Myung-Ki Cheoun, Kyungsik Kim +1
We construct new effective interactions using the relativistic mean-field models with the isoscalar- and isovector-meson mixing, and . Taking in…
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…
U(1) spin Chern-Simons theory and Arf invariants in two dimensions
Takuya Okuda, Koichi Saito, Shuichi Yokoyama
The level-k U(1) Chern-Simons theory is a spin topological quantum field theory for k odd. Its dynamics is captured by the 2d CFT of a compact boson with a certain radius. Recently…
Fock contributions to nuclear symmetry energy and its slope parameter based on Lorentz-covariant decomposition of nucleon self-energies
Tsuyoshi Miyatsu, Myung-Ki Cheoun, Chikako Ishizuka +3
Using relativistic Hartree-Fock (RHF) approximation, we study the effect of Fock terms on the nuclear properties not only around the saturation density, , but also at higher…
Equation of state for hybrid stars with strangeness
Tsuyoshi Miyatsu, Takahide Kambe, Koichi Saito
Considering the mass constraint from the resent pulsar observations, we study the properties of neutron stars including hyperons and quarks explicitly. Using the chiral quark-meson…
Equation of state for neutron star matter with NJL model and Dirac-Brueckner-Hartree-Fock approximation
Takahide Kambe, Tetsuya Katayama, Koichi Saito
As the interior density of a neutron star can become very high, it has been expected and discussed that quark matter may exist inside it. To describe the transition from hadron to…
