The paper AdS3/CFT2 and q-Poincare’ superalgebras
co-authored by Joakim Strömwall and Alessandro Torrielli, has been accepted for publication in the Journal of Physics A. In the paper they discover that a certain deformation of the 1+1 dimensional Poincare’ superalgebra is exactly realised in the massless sector of the AdS3/CFT2 integrable scattering problem. They obtain a representation of the boost operator and its coproduct, and show that the comultiplication exactly satisfies the homomorphism property. A classical limit is presented, and the paper speculates on an analogy with the physics of phonons.
