Lamb shift of rotational energy levels in quantum gravity
Oliver Benz, Marius Krumm, Wolfgang Wieland
One of the major challenges of modern foundational physics is the combination of quantum physics and general relativity into a theory of quantum gravity. A severe obstacle are the…
Topological field theory plus local Lorentz symmetry is gravity
Maïté Dupuis, Florian Girelli, Oleksandra Hrytseniak +1
Four-dimensional gravity admits many equivalent formulations - metric, Einstein-Cartan, teleparallel, McDowell-Mansouri, among others - each offering distinct advantages, particula…
Fermionisation of the Aharonov--Bohm Phase on the Lightfront
Carolina Sole Panella, Wolfgang Wieland
We consider the phase space of the Maxwell field as a simplified framework to study the quantisation of holonomies (Wilson line operators) on lightlike (null) surfaces. Our results…
Foundational Structure of Local Amplitudes in Quantum Gravity
Charalampos Theofilis, Wolfgang Wieland
There has been recently renewed interest in the quantisation of gravity by considering local subsystems on light-like hypersurfaces. The main purpose of this paper is to present a…
Quantum Geometry of the Light Cone: Fock representation and Spectrum of Radiated Power
Wolfgang Wieland
Starting from the symplectic potential for the -Palatini--Holst action on a null hypersurface, we identify an auxiliary conformal field theory (CFT), which carries a representat…
Linking Edge Modes and Geometrical Clocks in Linearized Gravity
Kristina Giesel, Viktoria Kabel, Wolfgang Wieland
Reference frames are crucial for describing local observers in general relativity. In quantum gravity, different proposals exist for how to treat reference frames. There are models…
Evidence for Planck Luminosity Bound in Quantum Gravity
Wolfgang Wieland
Recently, we introduced a non-perturbative quantization of impulsive gravitational null initial data. In this note, we investigate an immediate physical implication of the model. O…
Quantum geometry of the null cone
Wolfgang Wieland
We present a non-perturbative quantization of gravitational null initial data. Our starting point is the characteristic null initial problem for tetradic gravity with a parity-odd…
