High Energy Theory Seminar

I will describe a new approach to determining the bulk geometry from a dual field theory. This is based on a special class of spacelike cross-sections of the boundary called light-cone cuts. I will first show that the conformal metric in the bulk (i.e. the metric up to an overall conformal factor) can be reconstructed just from the location of these cuts, and then show how the light-cone cuts can be determined from the dual field theory. Finally I will discuss how (at least in some cases) the conformal factor can also be determined. These results were obtained in collaboration with Netta Engelhardt.
