A general framework for gravitational charges and holographic renormalization
Venkatesa Chandrasekaran, Eanna E. Flanagan, Ibrahim Shehzad +1
We develop a general framework for constructing charges associated with diffeomorphisms in gravitational theories using covariant phase space techniques. This framework encompasses…
Conservation of asymptotic charges from past to future null infinity: Lorentz charges in general relativity
Kartik Prabhu, Ibrahim Shehzad
We show that the asymptotic charges associated with Lorentz symmetries on past and future null infinity match in the limit to spatial infinity in a class of asymptotically-flat spa…
Brown-York charges at null boundaries
Venkatesa Chandrasekaran, Eanna E. Flanagan, Ibrahim Shehzad +1
The Brown-York stress tensor provides a means for defining quasilocal gravitational charges in subregions bounded by a timelike hypersurface. We consider the generalization of this…
The Wald-Zoupas prescription for asymptotic charges at null infinity in general relativity
Alexander M. Grant, Kartik Prabhu, Ibrahim Shehzad
We use the formalism developed by Wald and Zoupas to derive explicit covariant expressions for the charges and fluxes associated with the Bondi-Metzner-Sachs symmetries at null inf…
