Quasi-local mass on rigid or round spheres in Kerr spacetime
Jacek Jezierski, Tomasz Smołka
We introduce and analyze quasi-local mass using Hamiltonian methods. It is based on multipole decomposition for surfaces that are topological spheres. Based on the above model, tes…
Interacting Kerr-Newman Electromagnetic Fields
Sajad Aghapour, Lars Andersson, Kjell Rosquist +1
In this paper, we study some of the properties of the limit of the Kerr-Newman solution of Einstein-Maxwell equations. Noting Carter's observation of the near equality be…
Hopfion-like solutions in de Sitter spacetime
Adam Grzela, Jacek Jezierski, Tomasz Smołka
We construct electromagnetic field with non-trivial topological properties on de Sitter background. The field is closely related with Hopf fibration. We analyze energy, angular mom…
Hamiltonian charges on light cones for linear field theories on (A)dS backgrounds
Piotr T. Chruściel, Tomasz Smołka
We analyse the Noether charges for scalar and Maxwell fields on light cones on a de Sitter, Minkowski, and anti-de Sitter backgrounds. Somewhat surprisingly, under natural asymptot…
On the canonical energy of weak gravitational fields with a cosmological constant
P. T. Chruściel, Sk J. Hoque, M. Maliborski +1
We analyse the canonical energy of vacuum linearised gravitational fields on light cones on a de Sitter, Minkowski, and Anti de Sitter backgrounds in Bondi gauge. We derive the ass…
Quasi-local instantaneous charges asymptotics at spatial infinity
Jacek Jezierski, Tomasz Smołka
The article aims to analyze a construction of charges (conserved quantities) for the gravity field in the (3+1) decomposition. The construction is based on (3+1) splitting of confo…
Energy of weak gravitational waves in spacetimes with a positive cosmological constant
P. T. Chruściel, Sk Jahanur Hoque, Tomasz Smołka
We derive a formula for the total canonical energy, and its flux, of weak gravitational waves on a de Sitter background.
Simple description of generalized electromagnetic and gravitational hopfions
Tomasz Smołka, Jacek Jezierski
The generalization of electromagnetic and gravitational hopfions is performed in terms of a complex scalar field. New definition of topological charge for linearized gravity is giv…
A geometric description of Maxwell field in a Kerr spacetime
Jacek Jezierski, Tomasz Smołka
We consider the Maxwell field in the exterior of a Kerr black hole. For this system, we propose a geometric construction of generalized Klein-Gordon equation called Fackerell-Ipser…
