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…
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…
