Emergent symmetries and coexisting orders in Dirac fermion systems
Emilio Torres, Lukas Weber, Lukas Janssen +2
The quantum phase diagram and critical behavior of two-dimensional Dirac fermions coupled to two compatible order-parameter fields with symmetry is investigat…

Heisenberg-Kitaev Models on Hyperhoneycomb and Stripyhoneycomb Lattices: 3D-2D Equivalence of Ordered States and Phase Diagrams
Wilhelm G. F. Krüger, Matthias Vojta, Lukas Janssen
We discuss magnetically ordered states, arising in Heisenberg-Kitaev and related spin models, on three-dimensional (3D) harmonic honeycomb lattices. For large classes of ordered st…

Heisenberg-Kitaev physics in magnetic fields
Lukas Janssen, Matthias Vojta
Magnetic insulators in the regime of strong spin-orbit coupling exhibit intriguing behaviors in external magnetic fields, reflecting the frustrated nature of their effective intera…
