Interiors for AdS Black Holes

Wednesday, November 6th, 2019
Speaker: Sagar Lokhande, UIUC
I will start with a pedagogical review of the modern formulation of Black Hole Information Paradox. I will explain how this reformulation casts doubt on the smoothness of the event horizon and on the existence of a local effective field theory near the horizon. I will make brief comments on two prominent approaches to the resolution of the Paradox. Then, I will specialize to black holes in AdS spacetime and discuss the construction of interior operators for typical black holes. I will propose specific thought experiments involving out-of-time-order correlators (OTOC) that provide evidence for the existence of such operators. The AdS/CFT correspondence, a celebrated duality derived from string theory, plays a crucial role in this investigation. Finally, if time permits, I will discuss some work-in-progress to construct the interior operators for more general, non-typical AdS black holes using the theory of operator algebras.
