Nearly flat band with Chern number C=2 on the dice lattice
Motivated by recent experiments on the material Ba[subscript 3]NiSb[subscript 2]O[subscript 9], we consider a spin-one quantum antiferromagnet on a triangular lattice with the Heisenberg bilinear and biquadratic exchange interactions and a single-ion anisotropy. Using a fermionic "triplon"...
