Popis: Abstract One of the few cases of AdS/CFT where both sides of the duality are under good control relates tensionless k = 1 strings on AdS3 to a two-dimensional symmetric product CFT. Building on prior observations, we propose 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 k = 1 AdS3 string while the spacetime dual is a single trace T T ¯ $$ T\overline{T} $$ -deformed symmetric orbifold theory. As evidence for the duality, we match the one-loop bulk and boundary torus partition functions. This correspondence provides a framework to both learn about quantum gravity beyond AdS and understand how to define physical observables in T T ¯ $$ T\overline{T} $$ -deformed field theories.
