Meson resonance gas in a relativistic quark model: scalar vs vector confinement and semishort range correlations
Toru Kojo, Daiki Suenaga
Smooth transitions from hadronic matter to hot and dense matter of quantum chromodynamics accompany continuous transformations in effective degrees of freedom. The microscopic desc…
Impacts of anomaly on nuclear and neutron star equation of state based on a parity doublet model
Bikai Gao, Takuya Minamikawa, Toru Kojo +1
We examine the role of the anomaly in a parity doublet model of nucleons which include the chiral variant and invariant masses. Our model expresses the anomaly by…
Equation of state in neutron stars and supernovae
Kohsuke Sumiyoshi, Toru Kojo, Shun Furusawa
Neutron stars and supernovae provide cosmic laboratories of highly compressed matter at supra nuclear saturation density which is beyond the reach of terrestrial experiments. The p…
Merger and post-merger of binary neutron stars with a quark-hadron crossover equation of state
Yong-Jia Huang, Luca Baiotti, Toru Kojo +6
Fully general-relativistic binary-neutron-star (BNS) merger simulations with quark-hadron crossover (QHC) equations of state (EOSs) are studied for the first time. In contrast to E…
Chiral condensates for neutron stars in hadron-quark crossover; from a parity doublet nucleon model to an NJL quark model
Takuya Minamikawa, Toru Kojo, Masayasu Harada
In this contribution, we summarize our recent studies on the chiral invariant mass and the chiral condensates in neutron star matter. We construct a unified equations of state assu…
