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…

Phase structure of spin-imbalanced unitary Fermi gases

I. Boettcher, J. Braun, T. K. Herbst +3

We investigate the phase structure of spin-imbalanced unitary Fermi gases beyond mean-field theory by means of the Functional Renormalization Group. In this approach, quantum and t…

Zero-temperature equation of state of mass-imbalanced resonant Fermi gases

Jens Braun, Joaquín E. Drut, Dietrich Roscher

We calculate the zero-temperature equation of state of mass-imbalanced resonant Fermi gases in an ab initio fashion, by implementing the recent proposal of imaginary-valued mass di…

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…

Phases of spin- and mass-imbalanced ultracold Fermi gases in harmonic traps

Jens Braun, Joaquín E. Drut, Thomas Jahn +2

We analyze the phase structure of mass- and spin-imbalanced unitary Fermi gases in harmonic traps. To this end, we employ Density Functional Theory in the local density approximati…
