Chiral density wave versus pion condensation in the (1+1)dimensional NJL model
Andersen, Jens Oluf; Adhikari, Prabal (Journal article; Peer reviewed, 2017)In this paper, we study the possibility of an inhomogeneous quark condensate in the (1 þ 1)dimensional NambuJonaLasinio model in the largeNc limit at finite temperature T and quark chemical potential μ using dimensional ... 
Condensates and pressure of twoflavor chiral perturbation theory at nonzero isospin and temperature
Andersen, Jens Oluf; Mojahed, Martin Aria; Adhikari, Prabal (Peer reviewed; Journal article, 2021)We consider twoflavor chiral perturbation theory (χPT) at finite isospin chemical potential μI and finite temperature T . We calculate the effective potential and the quark and pion condensates as functions of T and μI ... 
Consistent regularization and renormalization in models with inhomogeneous phases
Andersen, Jens Oluf; Adhikari, Prabal (Journal article; Peer reviewed, 2017)In many models in condensed matter and highenergy physics, one finds inhomogeneous phases at high density and low temperature. These phases are characterized by a spatially dependent condensate or order parameter. A proper ... 
Inhomogeneous chiral condensate in the quarkmeson model
Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2017)The twoflavor quarkmeson model is used as a lowenergy effective model for QCD to study inhomogeneous chiral condensates at finite baryon chemical potential μB . The parameters of the model are determined by matching the ...

Pion condensation and phase diagram in the Polyakovloop quarkmeson model
Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2018)We use the Polyakovloop extended twoflavor quarkmeson model as a lowenergy effective model for QCD to study the phase diagram in the μI–T plane where μI is the isospin chemical potential. In particular, we focus on the ...
