Glue-on AdS holography for $T\bar{T}$-deformed CFTs

Abstract

The $T\bar{T}$ deformation is a solvable irrelevant deformation whose properties depend on the sign of the deformation parameter $\mu$. In particular, $T\bar{T}$-deformed CFTs with $\mu <0$ have been proposed to be holographically dual to Einstein gravity where the metric satisfies Dirichlet boundary conditions at a finite cutoff surface. In this paper, we put forward a holographic proposal for $T\bar{T}$-deformed CFTs with $\mu >0$, in which case the bulk geometry is constructed by gluing a patch of AdS${}_3$ to the original spacetime. As evidence, we show that the $T\bar{T}$ trace flow equation, the spectrum on the cylinder, and the partition function on the torus and the sphere, among other results, can all be reproduced from bulk calculations in glue-on AdS${}_3$.
