Recent observations of neutron stars, combined with causality, thermodynamic stability, and nuclear constraints, indicate a rapid stiffening of QCD matter at densities slightly above nuclear saturation density (n0 = 0.16fm-3). The evolution of the stiffening is faster than expected from purely nucleonic models with many-body repulsion. Taking into account the quark substructure of baryons, we...

The hadron-quark crossover (HQC) is one of the most exciting topics in nuclear astrophysics. Recently, microscopic features of HQC have been discussed in terms of the quarkyonic matter picture. In this talk, we address this problem from an Interdisciplinary context, by drawing an analogy with pairing fluctuations in the Bardeen-Cooper-Schrieffer to the Bose-Einstein condensate crossover,...

We investigate dense nuclear matter within a unified framework that combines the quarkyonic picture with the quark-meson coupling (QMC) model, focusing on symmetric and isospin-asymmetric nuclear matter. Nucleons are described explicitly at the quark level using relativistic Gaussian quark wavefunctions, providing a microscopic realization of a dual baryon-quark description of dense matter....

We investigate the equation of state of neutron-star matter using color–spin molecular dynamics, explicitly incorporating the internal color and spin degrees of freedom of quarks and their dynamical evolution. Flavor conversion processes, including the emergence of strangeness, as well as beta equilibrium, are determined self-consistently through energy minimization. Our results show that, in...
