Abstract

Almost twenty years ago, J.Maldacena made a remarkable insight into the structure of both quantum field theories and quantum gravity called the AdS/CFT correspondence. Its most intriguing feature is that the (Anti de Sitter) gravity theory involved has one more spatial dimension than the (Conformal) Field Theory to which it is physically equivalent. This is reminiscent of a hologram, like the 3D picture of you on your 2D driver's licence. Furthermore, AdS physics is easy to calculate when CFT physics is not, and vice versa. This sparked applications to modelling systems as diverse as quantum critical points in condensed matter, the quark-gluon plasma, and cosmology. Other advances developed conceptual connections between the geometry of spacetime and information theoretic entanglement. Our specific focus is on using holographic CFT tools to make progress on two grand puzzles: how do classical black hole spacetimes emerge from quantum string theory, and how can information that falls into black holes be recovered? This talk will assume no prior knowledge of any of these topics.
