The Weyl BMS group and Einstein's equations
A bstract We propose an extension of the BMS group, which we refer to as Weyl BMS or
BMSW for short, that includes super-translations, local Weyl rescalings and arbitrary …

Extended corner symmetry, charge bracket and Einstein's equations
A bstract We develop the covariant phase space formalism allowing for non-vanishing flux,
anomalies, and field dependence in the vector field generators. We construct a charge …

The partial Bondi gauge: Further enlarging the asymptotic structure of gravity
We present a detailed analysis of gravity in a partial Bondi gauge, where only the three
conditions $ g_ {rr}= 0= g_ {rA} $ are fixed. We relax in particular the so-called determinant …

Carroll black holes
Despite the absence of a lightcone structure, some solutions of Carroll gravity show black
hole-like behaviour. We define Carroll black holes as solutions of Carroll gravity that exhibit …

Isolated surfaces and symmetries of gravity
L Ciambelli, RG Leigh - Physical Review D, 2021 - APS
Conserved charges in theories with gauge symmetries are supported on codimension-2
surfaces in the bulk spacetime. It has recently been suggested that various classical …
