Abstract:

One of the most remarkable advances in our understanding of quantum gravity has been the development of the AdS/CFT correspondence, which provides a concrete realization of the holographic principle. But many believe that holography is more general than AdS/CFT and could be extended to gravity theories with different asymptotic behavior. In this talk I will highlight some recent advances in flat space holography. In particular, I will focus on the relation between pure Einstein gravity in three dimensions and a two dimensional quantum field theory with so-called Galilean conformal symmetry. We'll discuss how we can compute all boundary stress tensor n-point correlation functions recursively in both the bulk and boundary and hence provide a check for a 3D/2D flat space holographic correspondence.
