Field-dependent diffeomorphisms and the transformation of surface charges between gauges
Luca Ciambelli, Marc Geiller
When studying gauge theories in the presence of boundaries, local symmetry transformations are typically classified as gauge or physical depending on whether the associated charges…

Symmetries of the gravitational scattering in the absence of peeling
Marc Geiller, Alok Laddha, Céline Zwikel
The symmetries of the gravitational scattering are intimately tied to the symmetries which preserve asymptotic flatness at null infinity. In Penrose's definition of asymptotic flat…

Radiative Asymptotic Symmetries of 3D Einstein-Maxwell Theory
Jorrit Bosma, Marc Geiller, Sucheta Majumdar +1
We study the null asymptotic structure of Einstein-Maxwell theory in three-dimensional (3D) spacetimes. Although devoid of bulk gravitational degrees of freedom, the system admits…
