Lessons from the information paradox
S Raju - Physics Reports, 2022 - Elsevier
We review recent progress on the information paradox. We explain why exponentially small
correlations in the radiation emitted by a black hole are sufficient to resolve the original …

Carrollian perspective on celestial holography
We show that a 3D sourced conformal Carrollian field theory has the right kinematic
properties to holographically describe gravity in 4D asymptotically flat spacetime. The …

Scattering amplitudes: celestial and Carrollian
Recent attempts at the construction of holography for asymptotically flat spacetime have
taken two different routes. Celestial holography, involving a two dimensional (2D) conformal …

A non-lorentzian primer
We review both the kinematics and dynamics of non-lorentzian theories and their associated
geometries. First, we introduce non-lorentzian kinematical spacetimes and their symmetry …

The holographic nature of null infinity
We argue that, in a theory of quantum gravity in a four dimensional asymptotically flat
spacetime, all information about massless excitations can be obtained from an infinitesimal …
