Some recent progress on spacetime reconstruction from CFT

After discussing past developments on writing down a boundary operator to bulk field map in the framework of AdS/CFT, we discuss some recent and ongoing progress on constructing the background spacetime metric itself. In particular, we discuss how the ideas of boundary entanglement structure can be utilized to read off the (asymptotically) AdS geometry in one higher dimension. We discuss extending our construction at order by order in boundary perturbation theory and finally comment on the non-perturbative effects.
