摘　　要：In this study,based on the Ryu-Takayanagi formula,by identifying the pure state UV and IR entanglement entropies of a perturbed CFT_(2)with geodesic lengths in the bulk,we demonstrate that the dual geometry is uniquely determined to be asymptotically AdS_(3).The pure AdS3 geometry is recovered by taking the massless limit of the system.Our derivations hold in both static and covariant scenarios.
