Precision holography with higher spin theories
Speaker:Alejandra Castro (McGill University Montreal)
Abstract:In this talk I will give a short survey of higher spin theories in AdS spacetime. Vasiliev's higher spin theories provide a new venue to examine our expectations about quantum gravity. In relation to the holographic principle, this setup has allowed us to investigate in more depth the dictionary and consequences of this correspondence. The dual conformal theories are in principle solvable, and hence it opens the possibility of tracking the emergence of space-time from the boundary theory, among other effects. Our focus here will be in the three-dimensional version of AdS higher spin gravity, and hence its two-dimensional dual CFT. This is arguably the simplest setup of the correspondence from the bulk point of view, which has allowed a better understanding of physical phenomena in Vasiliev theory. The main topic to be discussed are the spectrum of both the bulk and boundary theory.
