Multipartite Edge Modes and Tensor Networks

Holographic tensor networks model AdS/CFT, but so far they have been limited by involving only systems that are very different from gravity. Unfortunately, we cannot straightforwardly discretize gravity to incorporate it, because that would break diffeomorphism invariance. In this talk I will present a resolution, based on upcoming work. We construct a tensor network with new gravity-like properties, and which does not suffer from the "commuting areas" problem of other tensor networks.
