The classical dynamics of gauge theories in the deep infrared
Eanna E. Flanagan, Ibrahim Shehzad
Gauge and gravitational theories in asymptotically flat settings possess infinitely many conserved charges associated with large gauge transformations or diffeomorphisms that are n…
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…
Asymptotic symmetries and charges at spatial infinity in general relativity
Kartik Prabhu, Ibrahim Shehzad
We analyze the asymptotic symmetries and their associated charges at spatial infinity in -dimensional asymptotically-flat spacetimes. We use the covariant formalism of Ashtekar…
Extensions of the asymptotic symmetry algebra of general relativity
Éanna É. Flanagan, Kartik Prabhu, Ibrahim Shehzad
We consider a recently proposed extension of the Bondi-Metzner-Sachs algebra to include arbitrary infinitesimal diffeomorphisms on a (2)-sphere. To realize this extended algebra as…
The holographic dual of Rényi relative entropy
Ning Bao, Mudassir Moosa, Ibrahim Shehzad
The relative entropy is a measure of the distinguishability of two quantum states. A great deal of progress has been made in the study of the relative entropy between an excited st…
Is volume the holographic dual of fidelity susceptibility?
Mudassir Moosa, Ibrahim Shehzad
It was proposed by Miyaji et al. that the fidelity susceptibility of a state of a conformal field theory under a marginal deformation is holographically dual to the volume of a max…
