Asymptotic charges from soft scalars in even dimensions
Miguel Campiglia, Leonardo Coito
We study asymptotic charges associated to a spin-zero analogue of Weinberg's soft photon and graviton theorems in even dimensions. Simple spacetime expressions for the charges are…
Quantum fluctuating geometries and the information paradox
Rodrigo Eyheralde, Miguel Campiglia, Rodolfo Gambini +1
We study Hawking radiation on the quantum space-time of a collapsing null shell. We use the geometric optics approximation as in Hawking's original papers to treat the radiation. T…
Asymptotic charges at spatial infinity
Miguel Campiglia, Rodrigo Eyheralde
Large gauge symmetries in Minkowski spacetime are often studied in two distinct regimes: either at asymptotic (past or future) times or at spatial infinity. By working in harmonic…
Can scalars have asymptotic symmetries?
Miguel Campiglia, Leonardo Coito, Sebastian Mizera
Recently it has been understood that certain soft factorization theorems for scattering amplitudes can be written as Ward identities of new asymptotic symmetries. This relationship…
