Joint Seminar

This a joint online video seminar series on theoretical and mathematical physics organized together by the ASC and the universities of Heidelberg and Vienna via a BigBlueButton interface.

It will take place on Mondays at 15:15.

If you are interested to participate, please send an email toIlka Brunner.

12.04. Shota Komatsu (CERN) "Three tales of de Sitter"
Abstract:
Based on works (to appear) with Lorenzo Di Pietro (Trieste) and Victor Gorbenko (Stanford). I will discuss several novel perspectives on quantum field theory in de Sitter spacetime and dS/CFT. The topics to be discussed include 1. Description of the dual CFT that directly produces the late-time correlation functions (rather than the wave functions). 2. New connection to theories in AdS. 3. Unitarity and analyticity of the late-time correlation functions.
