Advances in 2D Holography: From Near-Extremal Black Holes to JT Gravity - Lecture 2

Explore the second lecture in a five-part series on advances in 2D holography, focusing on the transition from near-extremal black holes to JT gravity. Delve into the quantum effects in the gravitational path integral that have provided a more accurate understanding of black hole behavior near extremality. Examine how the fluctuations of JT gravity modes lead to significant corrections in black hole entropy. Learn about the developments in both supersymmetric and non-supersymmetric black holes, and discover how JT gravity serves as a toy model for holography. Investigate the connection between JT gravity and matrix integrals, and understand how this relationship addresses various versions of the black hole information paradox. This 2-hour and 15-minute lecture, delivered by Luca Iliesiu from Stanford University, is part of a comprehensive course that covers black hole thermodynamics, perturbative corrections to black hole entropy, and the implications for the black hole information paradox.
