Global phase diagram of a spin–orbit-coupled Kondo lattice model on the honeycomb lattice |
Energy spectra of (a) the trivial AFMz state, (b) the topological AFMz insulator, and (c) the AFMxy state from finite slab calculations. Black lines denote the bulk states and red lines denote the edge states. The topological AFMz state is characterized by the gapless edge states. See text for detailed information on the parameters. |
