Description

We present a novel unified approach to describe the dense symmetric nuclear matter by combining the quarkyonic matter framework with the parity doublet model. This integration allows for a consistent treatment of
the transition from hadronic to quark degrees of freedom while incorporating chiral symmetry restoration effects. Our model introduces a chiral invariant mass for both baryons and constituent quarks, enabling a smooth
crossover between hadronic and quark matter in symmetric nuclear matter. We derive the equation of state
(EOS) for this hybrid system and investigate its thermodynamic properties. The model predicts a gradual onset
of quark degrees of freedom at high densities while maintaining aspects of confinement.
