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…
Chiral perturbation theory and Bose-Einstein condensation in QCD
Jens O. Andersen, Martin Kjøllesdal Johnsrud, Qing Yu +1
We present recent results in three-flavor chiral perturbation theory at finite isospin and strangeness chemical potentials at zero temperature. The phase diagram to $…
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…
