Explore the intricacies of extremal black holes in Anti-de Sitter (AdS) supergravity through this comprehensive lecture by Finn Larsen at the International Centre for Theoretical Sciences. Delve into the instability of these fascinating cosmic structures as part of the "Quantum Information, Quantum Field Theory and Gravity" program. Gain insights into the intersection of quantum gravity, quantum information theory, and many-body physics from a leading expert in the field. Examine topics such as the AdS/CFT correspondence, spacetime emergence, quantum error correction, and their implications for understanding black hole physics and information scrambling in chaotic quantum systems.
