Near-extremal black holes and Jackiw-Teitelboim gravity

Ashish Shukla

University of Victoria

In this talk I will discuss the dynamics of near-extremal Reissner-Nordstrom black holes in four-dimensional asymptotically AdS spacetime. Working in the spherically symmetric approximation, I will present results about the thermodynamics and the response of the system to a probe scalar field. I will present evidence that the dynamics in the low energy limit is very well captured by the two-dimensional Jackiw-Teitelboim (JT) theory of gravity, to the leading order in the appropriate parameters. The reason behind the efficacy of JT gravity for near-extremal black holes can be understood based on symmetry principles.
