Density functional approach to quark matter with confinement and color superconductivity

We present a novel relativistic density-functional approach to modeling quark matter with mechanism mimic confinement. The quasiparticle treatment of quarks provides their suppression due large selfenergy already at the mean-field level. demonstrate that our is equivalent chiral model medium-dependent couplings. dynamical restoration symmetry ensured by construction density functional. Supplemented vector repulsion and diquark pairing applied construct hybrid quark-hadron EoS cold compact-star matter. study connection such stellar mass-radius relation tidal deformability. results are compared various observational constraints including NICER radius measurement PSR J0740+6620 deformability constraint from GW170817. shown be consistent constraints, still allowing for further improvement adjusting
