Higher spin dynamics in gravity and celestial symmetries
Laurent Freidel, Daniele Pranzetti, Ana-Maria Raclariu
In this paper we extract from a large- expansion of the vacuum Einstein's equations a dynamical system governing the time evolution of an infinity of higher-spin charges. Upon i…
Sub-subleading Soft Graviton Theorem from Asymptotic Einstein's Equations
Laurent Freidel, Daniele Pranzetti, Ana-Maria Raclariu
We identify in Einstein gravity an asymptotic spin- charge aspect whose conservation equation gives rise, after quantization, to the sub-subleading soft theorem. Our treatment r…
Gravity from symmetry: Duality and impulsive waves
Laurent Freidel, Daniele Pranzetti
We show that we can derive the asymptotic Einstein's equations that arises at order in asymptotically flat gravity purely from symmetry considerations. This is achieved by st…
Electromagnetic duality and central charge from first order formulation
Marc Geiller, Puttarak Jai-akson, Abdulmajid Osumanu +1
In the context of the infrared triangle there have been recent discussions on the existence and the role of dual charges. We present a new viewpoint on dual magnetic charges in …
Extended corner symmetry, charge bracket and Einstein's equations
Laurent Freidel, Roberto Oliveri, Daniele Pranzetti +1
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 bracket that ge…
The Weyl BMS group and Einstein's equations
Laurent Freidel, Roberto Oliveri, Daniele Pranzetti +1
We propose an extension of the BMS group, which we refer to as Weyl BMS or BMSW for short, that includes, besides super-translations, local Weyl rescalings and arbitrary diffeomorp…
