Abstract: (IOP)
We discover that a certain deformation of the 1+1 dimensional Poincaré superalgebra is exactly realised in the massless sector of the AdS3/CFT2{\mathrm{AdS}}_{3}/{\mathrm{CFT}}_{2} integrable scattering problem. Deformed Poincaré superalgebras were previously noticed to appear in the AdS5/CFT4{\mathrm{AdS}}_{5}/{\mathrm{CFT}}_{4} correspondence—which displays only massive excitations, but they were there only a partial symmetry. We obtain a representation of the boost operator and its coproduct, and show that the comultiplication exactly satisfies the homomorphism property. We present a classical limit, and finally speculate on an analogy with the physics of phonons.
