12:30 pm:

I will discuss recent work studying universal properties of gravity in anti-de Sitter (AdS) spacetime from the perspective of conformal field theory (CFT). Using the AdS/CFT correspondence, scattering with black holes can be rephrased in terms of correlation functions involving operators with large scaling dimension. I will present new methods for calculating these correlation functions in 2d CFTs which make the connection to black holes and gravity manifest. In particular, I will show that operators with large scaling dimension create a thermal background with the correct Hawking temperature, with interactions that can be described using new on-shell diagrams. I will then discuss the connection with eigenstate thermalization and the possibility of generalizing these results to theories in higher dimensions.
