Explore a high energy physics seminar where Sam Leutheusser from the Institute for Advanced Study delves into the emergence of classical geometry in quantum gravity through the lens of von Neumann algebras. Discover how the AdS/CFT correspondence demonstrates the emergence of "type III" algebras when local degrees of freedom in boundary CFT approach infinity. Learn about how these emergent boundary algebras encode physical operations in bulk subregions, establish the causal structure of bulk geometry, and enable non-local quantum tasks in boundary theory. Gain insights into the fundamental properties of quantum gravity and its relationship with classical physics through this advanced theoretical physics discussion.
