Simplicial Graviton from Selfdual Ashtekar Variables
Wolfgang Wieland
In perturbative gravity, it is straight-forward to characterize the two local degrees of freedom of the gravitational field in terms of a mode expansion of the linearized perturbat…

Corner symmetry and quantum geometry
Laurent Freidel, Marc Geiller, Wolfgang Wieland
By virtue of the Noether theorems, the vast gauge redundancy of general relativity provides us with a rich algebra of boundary charges that generate physical symmetries. These char…

Quantum Reference Frames at the Boundary of Spacetime
Viktoria Kabel, Časlav Brukner, Wolfgang Wieland
An analysis is given of the local phase space of gravity coupled to matter to second order in perturbation theory. Working in local regions with boundaries at finite distance, we i…
