Two-flavor chiral perturbation theory at nonzero isospin: Pion condensation at zero temperature
Prabal Adhikari, Jens O. Andersen, Patrick Kneschke
In this paper, we calculate the equation of state of two-flavor finite isospin chiral perturbation theory at next-to-leading order in the pion-condensed phase at zero temperature.…
Pion condensation and QCD phase diagram at finite isospin density
Jens O. Andersen, Prabal Adhikari, Patrick Kneschke
We use the Polyakov-loop extended two-flavor quark-meson model as a low-energy effective model for QCD to study 1) the possibility of inhomogeneous chiral condensates and its compe…
Bose-Einstein condensation and pion stars
Jens O. Andersen, Patrick Kneschke
Pion stars consisting of Bose-Einstein condensed charged pions have recently been proposed as a new class of compact stars. We use the two-particle irreducible effective action to…
Pion condensation and phase diagram in the Polyakov-loop quark-meson model
Prabal Adhikari, Jens O. Andersen, Patrick Kneschke
We use the Polyakov-loop extended two-flavor quark-meson model as a low-energy effective model for QCD to study the phase diagram in the -- plane where is the isospin…
Chiral density wave versus pion condensation at finite density
Jens O. Andersen, Patrick Kneschke
The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature , baryon chemical potential , and isospin…
Inhomogeneous phases at finite density in an external magnetic field
Jens O. Andersen, Patrick Kneschke
The two-flavor quark-meson model is used as a low-energy effective model for QCD to study inhomogeneous chiral condensates at finite quark chemical potential in a constant magn…
