Topological phase transitions in the non-Abelian honeycomb lattice
Topological phase transitions in the non-Abelian honeycomb lattice
Ultracold Fermi gases trapped in honeycomb optical lattices provide an intriguing scenario, where relativistic quantum electrodynamics (QED) can be tested. Here, we generalize this system to non-Abelian QED, where massless Dirac fermions interact with effective non-Abelian gauge fields. We show how in this setup a variety of topological phase transitions …
