报告人介绍：
We compute the Wilson loop in the AdS_3 Chern-Simons gravity theory and also the entanglement entropy in the boundary theory. Because the boundary theory with a quantum correction is not described by conformal field theory, the entanglement entropy has a deformation. We explicitly show that the Wilson lines on the sphere manifold and the entanglement entropy on the sphere manifold in the boundary theory both give the consistent deformation from the CFT2 at the one-loop order.
