Beyond the Tensionless Limit

Abstract: Turning on R-R flux in the tensionless string theory on AdS3xS3xT4 corresponds to deforming the dual symmetric product orbifold CFT. We can thus study the mixed flux background using perturbation theory in the CFT. We find an integrable structure, a dynamical spin chain, governing the perturbation for large twist. Furthermore, by studying the form of the eigenstates, we can see how the AdS3xS3 directions are contained in the orbifold of T4, away from the point with higher spin symmetry.
