Title: Emergent local physics in Quantum Gravity
Abstract: An important property for any candidate theory of quantum gravity is the emergence of classical geometry in an appropriate limit. We describe a framework to understand this emergence using von Neumann algebras as probes of local physics. In the context of the AdS/CFT correspondence, we demonstrate that many non-trivial "type III" algebras emerge in the limit where the number of local degrees of freedom of the boundary CFT becomes infinite. We argue that these non-trivial emergent boundary algebras: i) encode physical operations that can be performed in arbitrary bulk subregions, ii) are responsible for the causal structure of bulk geometry, and iii) describe how the boundary theory can perform non-local quantum tasks.
