SYMMETRY OF osp(m|n) SPIN CALOGERO–SUTHERLAND MODELS

Abstract

We introduce osp(m|n) spin Calogero–Sutherland models and find that the models have the symmetry of osp(m|n) half-loop algebra or Yangian of osp(m|n) if and only if the coupling constant of the model equals to .

Keywords:

• Calogero–Sutherland model
• spin generalization
• Lie superalgebra
• half-loop algebra symmetry
• Yangian symmetry
