SUMMARY:QFT Colloquium: Charlotte Sleight (U. Naples) "Holograms in the Sky
 : Lessons for de Sitter and Flat-space Holography from AdS/CFT" - 
DESCRIPTION:Speaker  Charlotte Sleight\, University of Naples\n\nTitle  H
 olograms in the Sky: Lessons for de Sitter and Flat-space Holography from 
 AdS/CFT\n\nAbstract\nThe AdS/CFT correspondence is our most successful wor
 king example of the holographic principle in quantum gravity\, which ident
 ifies quantum gravity in anti-de Sitter space with a non-gravitational con
 formal field theory living on its boundary at infinity. I will discuss how
  far lessons from AdS/CFT can be pushed toward space-times closer to our u
 niverse\, using AdS’s maximally symmetric cousins\, de Sitter and Minkow
 ski space\, as a starting point. A key hurdle for holography in these set
 tings is that the physics involves outgoing radiation. I'll introduce a Eu
 clidean perspective that nevertheless allows us to recast observables in d
 e Sitter and flat space in terms of boundary correlators familiar from AdS
 /CFT\, providing a concrete bridge between radiative physics and standard 
 AdS tools.
