Quantum Gravity, Hydrodynamics and Emergent Cosmology: A Collection of Perspectives
Jibril Ben Achour, Dario Benedetti, Martin Bojowald +17
This collection of perspective pieces captures recent advancements and reflections from a dynamic research community dedicated to bridging quantum gravity, hydrodynamics, and emerg…
Diffeomorphisms as quadratic charges in 4d BF theory and related TQFTs
Marc Geiller, Florian Girelli, Christophe Goeller +1
We present a Sugawara-type construction for boundary charges in 4d BF theory and in a general family of related TQFTs. Starting from the underlying current Lie algebra of boundary…
Transition Amplitudes in 3D Quantum Gravity: Boundaries and Holography in the Coloured Boulatov Model
Christophe Goeller, Daniele Oriti, Gabriel Schmid
We consider transition amplitudes in the coloured simplicial Boulatov model for three-dimensional Riemannian quantum gravity. First, we discuss aspects of the topology of coloured…
Diffeomorphism-invariant observables and dynamical frames in gravity: reconciling bulk locality with general covariance
Christophe Goeller, Philipp A. Hoehn, Josh Kirklin
We describe a completely general and fully non-perturbative framework for constructing dynamical reference frames in generally covariant theories, and for understanding the gauge-i…
3d gravity in Bondi-Weyl gauge: charges, corners, and integrability
Marc Geiller, Christophe Goeller, Céline Zwikel
We introduce a new gauge and solution space for three-dimensional gravity. As its name Bondi-Weyl suggests, it leads to non-trivial Weyl charges, and uses Bondi-like coordinates to…
The Quantum Gravity Disk: Discrete Current Algebra
Laurent Freidel, Christophe Goeller, Etera R. Livine
We study the quantization of the corner symmetry algebra of 3d gravity, that is the algebra of observables associated with 1d spatial boundaries. In the continuum field theory, at…
Dual diffeomorphisms and finite distance asymptotic symmetries in 3d gravity
Marc Geiller, Christophe Goeller
We study the finite distance boundary symmetry current algebra of the most general first order theory of 3d gravity. We show that the space of quadratic generators contains diffeom…
Most general theory of 3d gravity: Covariant phase space, dual diffeomorphisms, and more
Marc Geiller, Christophe Goeller, Nelson Merino
We show that the phase space of three-dimensional gravity contains two layers of dualities: between diffeomorphisms and a notion of "dual diffeomorphisms" on the one hand, and betw…
Quasi-Local 3D Quantum Gravity : Exact Amplitude and Holography
Christophe Goeller
This thesis is dedicated to the study of quasi-local boundary in quantum gravity in the 3D space-time case. This research takes root in the holographic principle, which conjectures…
Non-Perturbative 3D Quantum Gravity: Quantum Boundary States and Exact Partition Function
Christophe Goeller, Etera R. Livine, Aldo Riello
We push forward the investigation of holographic dualities in 3D quantum gravity formulated as a topological quantum field theory, studying the correspondence between boundary and…
Probing the Shape of Quantum Surfaces: the Quadrupole Moment Operator
Christophe Goeller, Etera R. Livine
The standard toolkit of operators to probe quanta of geometry in loop quantum gravity consists in area and volume operators as well as holonomy operators. New operators have been d…
Quasi-local holographic dualities in non-perturbative 3d quantum gravity
Bianca Dittrich, Christophe Goeller, Etera R. Livine +1
We present a line of research aimed at investigating holographic dualities in the context of three dimensional quantum gravity within finite bounded regions. The bulk quantum geome…
Quasi-local holographic dualities in non-perturbative 3d quantum gravity II - From coherent quantum boundaries to BMS3 characters
Bianca Dittrich, Christophe Goeller, Etera Livine +1
We analyze the partition function of three-dimensional quantum gravity on the twisted solid tours and the ensuing dual field theory. The setting is that of a non-perturbative model…
Quasi-local holographic dualities in non-perturbative 3d quantum gravity I - Convergence of multiple approaches and examples of Ponzano-Regge statistical duals
Bianca Dittrich, Christophe Goeller, Etera Livine +1
This is the first of a series of papers dedicated to the study of the partition function of three-dimensional quantum gravity on the twisted solid torus with the aim to deepen our…
