Chiral condensates for neutron stars in hadron-quark crossover; from a parity doublet nucleon model to an NJL quark model

In this contribution, we summarize our recent studies on the chiral invariant mass and condensates in neutron star matter. We construct a unified equations of state assuming crossover phase transition from hadronic matter described by parity doublet model to quark an Nambu--Jona-Lasinio type model. first show that is constrained be $600\,\mbox{MeV}\, \lesssim\, m_0 \,\lesssim \, 900\,\mbox{MeV}$ observations stars. then determine density dependence condensate description, are actually smoothly connected where change driven positive scalar charge nucleon, modification Dirac sea, reflecting hadron-quark crossover.
