Single-particle properties of topological Wannier excitons in bismuth chalcogenide nanosheets
We analyze the topology, dispersion, and optical selection rules of bulk Wannier excitons in nanosheets of Bi(2)Se(3), a topological insulator in the family of the bismuth chalcogenides. Our main finding is that excitons also inherit the topology of the electronic bands, quantified by the skyrmion w...
