Cutoff AdS3 versus T T ¯ $$ T\overline{T} $$ CFT2 in the large central charge sector: correlators of energy-momentum tensor

Abstract In this article we probe the proposed holographic duality between T T ¯ $$ T\overline{T} $$ deformed two dimensional conformal field theory and the gravity theory of AdS3 with a Dirichlet cutoff by computing correlators of energy-momentum tensor. We focus on the large central charge sector of the T T ¯ $$ T\overline{T} $$ CFT in a Euclidean plane and a sphere, and compute the correlators of energy-momentum tensor using an operator identity promoted from the classical trace relation. The result agrees with a computation of classical pure gravity in Euclidean AdS3 with the corresponding cutoff surface, given a holographic dictionary which identifies gravity parameters with T T ¯ $$ T\overline{T} $$ CFT parameters.
