Holographic reconstruction of flat spacetime
Zezhuang Hao
The flat/CFT dictionary between the bulk gravitational theory and boundary conformal field theory is systematically developed in this paper. Asymptotically flat spacetime is built…

Real time holography for higher spin theories
Zezhuang Hao
Real time holography is studied in the context of the embedding space formalism. In the first part of this paper, we present matching conditions for on-shell integer spin fields wh…

Flat holography and celestial shockwaves
Zezhuang Hao, Marika Taylor
In this paper we systematically develop the flat/CFT holographic dictionary, building on AdS/CFT holography. After analysing the behaviour of scalar field modes on hyperbolic slice…
