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

The mass of a nucleon consists of chiral variant and invariant components. Since their medium properties are different, the composition can be examined through matter in extreme conditions such as neutron stars. Using a parity doublet model for nuclear matter, we study the mass composition of nucleons through construction of neutron star equations of state assuming crossover from hadron to quark. We discuss the density dependence of the chiral condensates in neutron stars.
