Inhomogeneous chiral condensate in the quark-meson model
Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2017-07-24) -
Inhomogeneous chiral condensate in the quark-meson model
Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article, 2017)The two-flavor quark-meson model is used as a low-energy effective model for QCD to study inhomogeneous chiral condensates at finite baryon chemical potential μ B. The parameters of the model are determined by matching the ... -
On-shell parameter fixing in the quark-meson model
Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2017-02)The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature T and baryon chemical potential μB. The parameters in the quark-meson model can be found by ... -
Pion condensation and phase diagram in the Polyakov-loop quark-meson model
Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2018-10)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 μI–T planewhere μI is the isospin chemical potential. In particular, we focus on the ... -
Pion condensation and QCD phase diagram at finite isospin density
Andersen, Jens Oluf; Adhikari, Prabal; Kneschke, Patrick (Journal article; Peer reviewed, 2019-09)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 competition with a homogeneous pion condensate ... -
Two-flavor chiral perturbation theory at nonzero isospin: Pion condensation at zero temperature
Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2019-10)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. We show that the transition from the vacuum ...
