Probing decoupled Throats of AdS Black Holes in
Weichao Bu, Yang Lei
The Kerr/CFT correspondence establishes a relationship between extremal black holes in higher dimensions and a chiral conformal field theory (CFT) in their near-horizon limit. A ge…

2d theory for asymptotic dynamics of 4d (self-dual) Einstein gravity
Wei Bu, Sean Seet
In this paper, we present a simple chiral 2d theory living on a momentum space celestial sphere whose behaviour exactly produces various IR dynamics of recent resurged interests fo…

Eikonal amplitudes on the celestial sphere
Tim Adamo, Wei Bu, Piotr Tourkine +1
Celestial scattering amplitudes for massless particles are Mellin transforms of momentum-space scattering amplitudes with respect to the energies of the external particles, and beh…
