Explore a 43-minute conference talk on superstring partition functions in AdS3 delivered by Mukund Rangamani from UC Davis at the Spacetime and String Theory conference. Delve into advanced topics in string theory, focusing on the intersection of quantum information, string compactification, and holographic dualities. Gain insights into non-perturbative string theory, stringy constraints on effective field theory, and the connections between gravitational path integrals, higher topologies, and entanglement. Recorded at the Kavli Institute for Theoretical Physics, this presentation contributes to a new synthesis of the field, bridging the gap between infrared and ultraviolet perspectives on the nature of spacetime.
