Long-Range Interactions in Celestial CFT
Sangmin Choi, Ameya Kadhe, Andrea Puhm
Loop corrections in QED and gravity have recently been conjectured to give rise to an infinite tower of logarithmic soft theorems governing the universal low-energy behavior of pho…

The Classical Super-Phaserotation Infrared Triangle
Sangmin Choi, Alok Laddha, Andrea Puhm
The universality of the logarithmic soft photon theorem in four dimensions can be traced to an infinite-dimensional asymptotic symmetry which acts as a local phase rotation on matt…

The Classical Super-Rotation Infrared Triangle
Sangmin Choi, Alok Laddha, Andrea Puhm
The universality of gravitational scattering at low energies and large distances encoded in soft theorems and memory effects can be understood from symmetries. In four-dimensional…
