演題:Lesson from a violation of CHSH inequality to holographic principle
要旨:
Holographic principle is a prominent appraoch to quantum gravity (QG), which is yet to be formulated. It is a duality between d-dimensional QG states in a bulk and (d-1)-dimensional quantum states on the boundary of the bulk. In the AdS/CFT correspondence, an example of holography, the quantum theory on the boundary of AdS is well-understood as conformal field theory. Thus, this duality enables us to understand QG, something we do not know well, from something familiar to us.
Nevertheless, it is far from straightforward to apply AdS/CFT to our universe as our universe (like dS) is different from AdS. To overcome this, dS/CFT, which is an analytic continuation of AdS/CFT, has been proposed 24 years ago. However, so far there is no proper justifcation for the analytic continuation and many works just assume dS/CFT. In this talk, I will talk about my on-going work on testing the validity of dS/CFT by checking the Tsirelson bound of the CHSH observable. I will discuss difficulty associated with infinite dimensions, how one will overcome it, violations in (A)dS/CFT, and subtleties in their interpretations.
