Reconstruction of an AdS radiation/boson star bulk geometry using light-cone cuts

Abstract

Abstract Light-cone cuts have recently been proposed as a method to reconstruct the conformal metric of a holographic spacetime. We explore how additional information about the bulk geometry gets encoded in the structure of these light-cone cuts. In particular, we study how the hyperbolic angle related to a cusp in the light-cone cut encodes information about the matter content of the spacetime. Combining this information with the mass obtained from an integral at the boundary, we provide an explicit numerical example reconstructing the metric for a 4-dimensional static and spherically symmetric spacetime composed by the superposition of a boson star and a gas of radiation in AdS.
