Holographic boundary conformal field theory with $T\bar{T}$ deformation

Abstract

We propose a holographic dual of boundary conformal field theory (BCFT) with $T\bar{T}$ deformation, i.e. of $T\bar{T}$ BCFT. Our holographic proposal distinguishes two types of $T\bar{T}$ BCFTs, depending on whether the $T\bar{T}$ deformation deforms the boundary. For the boundary-deformed case, we find that boundary entropy serves as an effective measure to quantify the impact of boundary deformation. In this scenario, we calculate the energy spectrum for the $T\bar{T}$ BCFT within a finite interval to support the proposed dual. For the boundary-undeformed case, we calculate the entanglement entropy and Rényi entropy from both the field theory side and the gravity side, and find that they match.
