IAS Quantum Aspects of Black Holes Group Meeting
A de Sitter Scrambling Algebra
Abstract: In previous work, Chandrasekaran, Longo, Penington, and Witten (CLPW) constructed an algebra for an observer in a de Sitter static patch. I will discuss how this algebra is affected by gravitational corrections. I will work in the eikonal approximation, which is valid when operators are time-separated by a scrambling time. I will present evidence that the algebra has a trivial commutant. This talk is based on work in progress with Wentao Cui.
