Exotic S=1 spin-liquid state with fermionic excitations on the triangular lattice
Motivated by recent experiments on the material Ba₃NiSb₂O₉, 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” representation for spins, we study the phase...
