Abstract
In this work, we investigate the entanglement structure in a \(\text{T}\overline{\text{T} }\)-deformed holographic CFT2 with a conserved angular momentum. We utilize conformal perturbation theory to compute the leading order correction to the entanglement entropy and the reflected entropy due to the \(\text{T}\overline{\text{T} }\) deformation in the limit of large central charge. In the dual bulk perspective described by a rotating BTZ black hole with a finite radial cut-off, we compute the holographic entanglement entropy and the entanglement wedge cross-section and observe perfect agreement with our field theoretic computation for small values of the deformation parameter.
