Entanglement entropy for TT deformed CFT in general dimensions

We consider deformation of a generic d dimensional (d >= 2) large-NCFT on a sphere by a spin-0 operator which is bilinear in the components of the stress tensor. Such a deformation has been proposed to be holographically dual to an AdS(d+1) bulk with a hard radial cut-off. We compute the exact partition function and find the entanglement entropy from the field theory side in various dimensions and compare with the corresponding holographic results. We also compute renormalized entanglement entropy both in field theory and holography and find complete agreement between them. (C) 2019 The Author(s). Published by Elsevier B.V.
