Constructing flat holography using AdS/CFT

Eliot Hijano of Princeton University will give the Stanford Institute for Theoretical Physics (SITP) Monday Colloquium.

AbstractIt is currently not well understood whether the holographic principle can be applied to asymptotically flat space-times. This talk considers a flat limit of AdS/CFT that leads to a formula relating S-matrix amplitudes in flat space and correlators in a conformal field theory. The limit translates flat physics into the language of conformal theory and holography. As an example, I will discuss soft theorems and IR finite definitions of the S-matrix.
