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…
Celestial charges and the subleading structure of asymptotically-flat spacetimes
Marc Geiller
We study the subleading structure of asymptotically-flat spacetimes and its relationship to the loop algebra of higher spin charges. We do so using both the Bondi-Sa…
The partial Bondi gauge: Gauge fixings and asymptotic charges
Marc Geiller, Céline Zwikel
In the companion paper [SciPost Phys. 13, 108 (2022), arXiv:2205.11401 [hep-th]] we have studied the solution space at null infinity for gravity in the partial Bondi gauge. This pa…
Minimal massive supergravity and new theories of massive gravity
Nihat Sadik Deger, Marc Geiller, Jan Rosseel +1
We present an action for minimal massive gravity (MMG) in three dimensions in terms of a dreibein and an independent spin connection. Furthermore, the construction provides an acti…
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…
3d gravity in Bondi-Weyl gauge: charges, corners, and integrability
Marc Geiller, Christophe Goeller, Céline Zwikel
We introduce a new gauge and solution space for three-dimensional gravity. As its name Bondi-Weyl suggests, it leads to non-trivial Weyl charges, and uses Bondi-like coordinates to…
