Vacuum Asymptotic Codes

I will review asymptotically isometric codes - a tool to take the large-N limit in holographic theories, allowing for non-trivial von Neumann algebras to act on the code as well as on the physical Hilbert space. I will then discuss a relationship between the CFT thermal partition function and the properties of entanglement wedges for disjoint boundary regions in the vacuum. Our results suggest a characterization of asymptotic codes with emergent sub-AdS locality.
