Quantum Gravity, the AdS/CFT Correspondence, and Self-Dual SpacetimesMichael Butler

Quantum gravity represents the efforts of several fields in physics to find a unified description of gravity that operates on all scales. The Anti-de Sitter space/conformal field theory (AdS/CFT) correspondence, or gauge/gravity duality, is the observation that some mappings exist between quantum field theories to specific descriptions of gravity under general relativity. In an endeavour to better understand these dualities metrics from M-theory are derived. These metrics describe a spacetime which can be examined to understand how that quantum representation of gravity behaves under Einstein’s field equations. Self-dual metrics are of particular interest as they represent these dualities in concise mathematical terms. This enables us to examine the associated gravitational models in useful test cases, such as blackholes, where quantum and gravitational physics converge. This talk will go over the concepts of gauge/gravity duality with a focus on self-dual metrics and their importance in establishing the connection between quantum and gravitational theories.
