Novel Phases and Chiral Interactions in Spin-1 Magnets*

Recent theoretical work has uncovered a rich and diverse array of physics in spin-1/2 systems with scalar 3-spin chiral interactions, including non-coplanar magnetic phases and Abelian chiral spin liquids. Spin-1 magnets offer even more exciting possibilities, with the capacity for a more complex order parameter structure and the possibility of realising non-Abelian chiral spin liquids, as predicted by studies of exact parent Hamiltonians. We will discuss the effects of scalar chiral interactions on spin-1 Heisenberg-biquadratic models in two dimensions, elucidating the new phases and exotic physics that emerges.
