Massive hybrid stars within the extended three-flavor quark-meson diquark model
Jens O. Andersen, Manuel Linares, Mathias P. Nødtvedt
We discuss the properties of the extended three-flavor quark-meson diquark (EQMD) model as a renormalizable low-energy effective model for QCD. The effective degrees of freedom are…
Quark-meson diquark model and color superconductivity in dense quark matter
Jens O. Andersen, Mathias P. Nødtvedt
We consider the two- and three-flavor QMD models as renormalizable low-energy models for QCD at finite quark chemical potentials with quarks, mesons, and diquarks as effective degr…
Renormalization of the three-flavor quark-meson diquark model
Jens O. Andersen, Mathias P. Nødtvedt
We discuss the properties of the two- and three-flavor quark-meson diquark (QMD) model as a renormalizable low-energy effective model for color superconductivity in dense QCD. The…
Pion condensation versus 2SC, speed of sound, and charge neutrality effects in the quark-meson diquark model
Jens O. Andersen, Mathias P. Nødtvedt
We employ the two-flavor quark-meson diquark model as a low-energy model for QCD at non-zero quark and isospin chemical potentials and , and at zero temperature. We map…
Color superconductivity and speed of sound in the two-flavor quark-meson diquark model
Jens O. Andersen, Mathias P. Nødtvedt
We discuss the properties of the two-flavor quark-meson diquark (QMD) model as a renormalizable low-energy model for QCD in the 2SC phase of QCD. The effective degrees of freedom a…
