Abstract Using the tensor Radon transform and related numerical methods, we study how bulk geometries can be explicitly reconstructed from boundary entanglement entropies in the specific case of AdS3/CFT2. We find that, given the boundary entanglement entropies of a 2d CFT, this framework provides a quantitative measure that detects whether the bulk dual is geometric in the perturbative (near AdS) limit. In the case where a well-defined bulk geometry exists, we explicitly reconstruct the unique bulk metric tensor once a gauge choice is made. We then examine the emergent bulk geometries for static and dynamical scenarios in holography and in many-body systems. Apart from the physics results, our work demonstrates that numerical methods are feasible and effective in the study of bulk reconstruction in AdS/CFT.

Gauge Choice

We have considered a superparticle action consisting of an infinite tower of Siegel superparticle actions plus a term breaking all the twisted N=2 supersymmetries down to the required N=1 supersymmetry. With appropriate gauge choice we arrive at a quadratic gauge-fixed action, which naturally possesses an infinite sequence of twisted N=2 supersymmetries, but the BRST operator picks out the correct physical states for the Brink-Casalbuoni-Schwarz superparticle.

Metric Fluctuations

A gauge invariant theory of gravitational fluctuations of brane-world model is presented. Without resorting to any specific gauge choice, a general method is presented in order to disentangle the fluctuations of the energy–momentum tensor of the brane from the fluctuations of the metric. The employed procedure is gauge-invariant at every step. As an application of the formalism we address the localization of metric fluctuations on scalar branes breaking spontaneously five-dimensional Poincaré invariance is addressed. Assuming that the four-dimensional Planck mass is finite and that the geometry is regular, it is demonstrated that the vector and scalar fluctuations of the metric are not localized on the brane.
