Abstract

One of the best understood AdS/CFT incarnations relates tensionless k=1 strings on AdS3 to a symmetric product CFT2. I will discuss an exact duality between string theory on a spacetime which is not asymptotically AdS and a non-conformal field theory. The bulk theory is constructed as a marginal deformation of the tensionless AdS3 string, while the spacetime dual is a single trace TTbar-deformed symmetric orbifold theory. As evidence for the duality, I am going to show the exact match of the one-loop bulk and boundary torus partition functions. If time allows, I will explain how a non-perturbative completion of the TTbar partition function naturally arises from the worldsheet.
