Exploring the first-order phase transition in neutron stars using the parity doublet model and a Nambu–Jona-Lasinio–type quark model
We investigate the possibility and impacts of a first-order phase transition from hadronic matter to quark matter in neutron stars (NSs) using two specific models: the parity doublet model for the hadronic phase and the Nambu--Jona-Lasinio--type model for the quark phase. By combining these models, we construct hybrid equations of state that capture the transition between the two phases. We explore the parameter space of both models to identify the conditions under which a first-order phase transition can occur and study its effects on NS properties. We identify the suitable parameter space and constrain the onset density of the first-order phase transition.
