Gravitational Algebra on the Light Cone
Wolfgang Wieland
In a region with a boundary, the gravitational phase space consists of radiative modes in the interior and edge modes at the boundary. Such edge modes are necessary to explain how…
Null infinity as an open Hamiltonian system
Wolfgang Wieland
When a system emits gravitational radiation, the Bondi mass decreases. If the Bondi energy is Hamiltonian, it can thus only be a time dependent Hamiltonian. In this paper, we show…
Twistor representation of Jackiw-Teitelboim gravity
Wolfgang Wieland
Jackiw-Teitelboim (JT) gravity is a 1+1-dimensional toy model for quantum gravity in four spacetime dimensions. In the absence of matter, JT gravity is a topological field theory a…
Deformed Heisenberg charges in three-dimensional gravity
Jeevan Chandra Namburi, Wolfgang Wieland
In this paper, we consider the bulk plus boundary phase space for three-dimensional gravity with negative cosmological constant for a particular choice of conformal boundary condit…
First-order formulation of teleparallel gravity and dual loop gravity
Maïté Dupuis, Florian Girelli, Abdulmajid Osumanu +1
There are at least two ways to encode gravity into geometry: Einstein's general theory of relativity (GR) for the metric tensor, and teleparallel gravity, where torsion as opposed…
Generating functional for gravitational null initial data
Wolfgang Wieland
A field theory on a three-dimensional manifold is introduced, whose field equations are the constraint equations for general relativity on a three-dimensional null hypersurface. Th…
