Abstract
The symmetric orbifold of T^4, Sym_N(T4), is dual to tensionless string theory on AdS3 x S3 x T4 with one unit of NS-NS flux. In this talk I will study the deformation of the symmetric orbifold theory that corresponds to switching on R-R flux (and hence the string tension) in the bulk string theory. Working in the planar large N limit as well as the limit of large charge, I will explain how the deformed symmetric orbifold theory can be explicitly solved in terms of what appears to be an integrable system. Among other things, this allows us to give explicit predictions about the anomalous conformal dimensions of all multi-magnon states.
