Crystalline Ground States in Polyakov-loop extended Nambu--Jona-Lasinio Models
Jens Braun, Felix Karbstein, Stefan Rechenberger +1
Nambu--Jona-Lasinio-type models have been used extensively to study the dynamics of the theory of the strong interaction at finite temperature and quark chemical potential on a phe…
On the Search for Inhomogeneous Phases in Fermionic Models
Jens Braun, Stefan Finkbeiner, Felix Karbstein +1
We revisit the Gross-Neveu model with N fermion flavors in 1+1 dimensions and compute its phase diagram at finite temperature and chemical potential in the large-N limit. To this e…
On the Phase Structure of Many-Flavor QED
Jens Braun, Holger Gies, Lukas Janssen +1
We analyze the many-flavor phase diagram of quantum electrodynamics (QED) in 2+1 (Euclidean) space-time dimensions. We compute the critical flavor number above which the theory is…
Renormalization Flow of Axion Electrodynamics
Astrid Eichhorn, Holger Gies, Dietrich Roscher
We study the renormalization flow of axion electrodynamics, concentrating on the non-perturbative running of the axion-photon coupling and the mass of the axion (like) particle. Du…
