Fractional spin liquid hierarchy for spin S antiferromagnets

Understand

We propose a hierarchy of spin liquids with spin S, which are generated via a Schwinger boson projection from 2S (Abelian) chiral spin liquids with S=1/2.

• We argue that the P and T invariant liquids we construct for integer spin S support SU(2) level k=S non-Abelian statistics.
• We conjecture that these spin liquids serve as paradigms for antiferromagnets which are disordered through mobile charge carriers.
