    • Conformal Sigma-Models on Supercoset Targets 

      Kagan, David; Young, Charles A. S. (2005-12-20)
      We investigate the quantum behaviour of sigma models on coset superspaces G/H defined by Z_{2n} gradings of G. We find that, whenever G has vanishing Killing form, there is a choice of WZ term which renders the model quantum ...

    • Multiplicity in Supersymmetric Spin Chains 

      Kagan, David; Young, Charles A. S. (2007-08-28)
      We discuss a simple procedure for obtaining new integrable spin chains from old by replacing each single state of the original model by some collection of states. This works whenever the Lax matrix of the chain has a certain ...
