Towards a phase diagram for spin foams
Clement Delcamp, Bianca Dittrich
One of the most pressing issues for loop quantum gravity and spin foams is the construction of the continuum limit. In this paper, we propose a systematic coarse-graining scheme fo…
On entanglement entropy in non-Abelian lattice gauge theory and 3D quantum gravity
Clement Delcamp, Bianca Dittrich, Aldo Riello
Entanglement entropy is a valuable tool for characterizing the correlation structure of quantum field theories. When applied to gauge theories, subtleties arise which prevent the f…
Coarse graining flow of spin foam intertwiners
Bianca Dittrich, Erik Schnetter, Cameron J. Seth +1
Simplicity constraints play a crucial role in the construction of spin foam models, yet their effective behaviour on larger scales is scarcely explored. In this article we introduc…
Fusion basis for lattice gauge theory and loop quantum gravity
Clement Delcamp, Bianca Dittrich, Aldo Riello
We introduce a new basis for the gauge-invariant Hilbert space of lattice gauge theory and loop quantum gravity in dimensions, the fusion basis. In doing so, we shift the f…
From 3D topological quantum field theories to 4D models with defects
Clement Delcamp, Bianca Dittrich
(2+1) dimensional topological quantum field theories with defect excitations are by now quite well understood, while many questions are still open for (3+1) dimensional TQFTs. Here…
Quantum gravity kinematics from extended TQFTs
Bianca Dittrich, Marc Geiller
We show how extended topological quantum field theories (TQFTs) can be used to obtain a kinematical setup for quantum gravity, i.e. a kinematical Hilbert space together with a repr…
