Constraining the competition between the deconfinement and chiral phase transitions in light of the multimessenger era
Wen-Li Yuan, Bikai Gao, Yan Yan +2
We extend the parity doublet model for hadronic matter and study the possible presence of quark matter inside the cores of neutron stars with the Nambu-Jona-Lasinio (NJL) model. Co…

Hybrid stars with large quark cores within the parity doublet model and modified NJL model
Wen-Li Yuan, Bikai Gao, Yan Yan +1
Using the parity doublet model (PDM) for hadronic matter and a modified Nambu-Jona-Lasinio (NJL) model for quark matter, we investigate the potential existence of two- and three-fl…

Hybrid Quark Stars with Quark-Quark Phase Transitions
Zongcan Yang, Tianxiong Zeng, Yan Yan +3
We explore the possibility of phase transitions between different quark matter phases occurring within quark stars, giving rise to the hybrid quark stars (HybQSs). First, we obtain…
