Chiral density wave versus pion condensation in the (1+1)-dimensional NJL model
(Journal article; Peer reviewed, 2017)In this paper, we study the possibility of an inhomogeneous quark condensate in the (1 þ 1)-dimensional Nambu-Jona-Lasinio model in the large-Nc limit at finite temperature T and quark chemical potential μ using dimensional ... -
Consistent regularization and renormalization in models with inhomogeneous phases
(Journal article; Peer reviewed, 2017)In many models in condensed matter and high-energy 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 ... -
N=4 supersymmetric Yang-Mills thermodynamics from effective field theory
(Peer reviewed; Journal article, 2022)The free energy density of N ¼ 4 supersymmetric Yang-Mills theory in four space-time dimensions is derived through second order in the ’t Hooft coupling λ at finite temperature using effective-field theory methods. The ... -
Pion condensation in QCD at finite isospin density, the dilute Bose gas, and speedy Goldstone bosons
(Journal article, 2024)We consider pion condensation in QCD at finite isospin density μI and zero temperature using two-flavor chiral perturbation theory (χPT). The pressure is calculated to next-to-leading order (NLO) in the low-energy expansion. ... -
Thermodynamics and phase diagrams of Polyakov-loop extended chiral models
(Journal article; Peer reviewed, 2019)We study the thermodynamics and phase diagrams of two-flavor quantum chromodynamics using the Polyakov-loop extended quark-meson (PQM) model and the Pisarski-Skokov chiral matrix (χM) model [1]. At temperatures up to T≈2Tc ...
