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…

Topological Mott insulator in three-dimensional systems with quadratic band touching
Igor F. Herbut, Lukas Janssen
We argue that a three dimensional electronic system with the Fermi level at the quadratic band touching point such as HgTe could be unstable with respect to the spontaneous formati…

Antiferromagnetic critical point on graphene's honeycomb lattice: A functional renormalization group approach
Lukas Janssen, Igor F. Herbut
Electrons on the half-filled honeycomb lattice are expected to undergo a direct continuous transition from the semimetallic into the antiferromagnetic insulating phase with increas…
