Bottom-up de Sitter holography
David Kolchmeyer,
Massachusetts Institute of Technology,
A holographic dual description of de Sitter space must be able to capture physics from an observer's point of view. Taking a bottom-up perspective, I compute correlation functions of operators dressed to an observer's worldline in de Sitter. Out-of-time-ordered correlators with long time separations exhibit an ``anti-scrambling'' property that is in tension with finite temperature quantum mechanics. I will also discuss the probability distribution for the observer's mass in the Hartle-Hawking state, which provides a fundamental constraint on the putative quantum dual.
