Representation Theory of Three-dimensional Corner Symmetries
Giulio Neri, Ludovic Varrin
We study the representation theory of the three-dimensional extended corner symmetry group associated with a circular corner. Using induced representation techniques, we construct…
Quantum Geometry from Area Fluctuations
Jerzy Kowalski-Glikman, Ludovic Varrin
We construct a quantum-statistical analogue of Einstein's fluctuation argument for black-body radiation in the context of causal-diamond geometry. Starting from the phase space of…
At the Corner of Quantum and Gravity
Ludovic Varrin
In the presence of spacetime boundaries, diffeomorphisms in gravitational theories can become physical and acquire non-vanishing Noether charges. These charges obey an algebra whic…
From the Corner Proposal to the Area Law
Jerzy Kowalski-Glikman, Ludovic Varrin
We provide an explicit realization of the Corner Proposal for Quantum Gravity in the case of spherically symmetric spacetimes in four dimensions, or equivalently, two-dimensional d…
Semi-Classical Limit of Quantum Gravity on Corners
Ludovic Varrin
We study quantum and classical systems associated with the quantum corner symmetry group which arises in t…
Entanglement Entropy of Quantum Corners
Luca Ciambelli, Jerzy Kowalski-Glikman, Ludovic Varrin
In gravitational theories with boundaries, diffeomorphisms can become physical and acquire a non-vanishing Noether charge. Using the covariant phase space formalism, on shell of th…
Orbit method for Quantum Corner Symmetries
Giulio Neri, Ludovic Varrin
The classification of the unitary irreducible representations of symmetry groups is a cornerstone of modern quantum physics, as it provides the fundamental building blocks for cons…
Physical Representations of Corner Symmetries
Ludovic Varrin
We give the full representation theory of the gravitational extended corner symmetry group in two-dimensions. This includes projective representations, which correspond to represen…
Quantum Corner Symmetry: Representations and Gluing
Luca Ciambelli, Jerzy Kowalski-Glikman, Ludovic Varrin
The corner symmetry algebra organises the physical charges induced by gravity on codimension- corners of a manifold. In this letter, we initiate a study of the quantum propertie…
On the covariant formulation of gauge theories with boundaries
Mehdi Assanioussi, Jerzy Kowalski-Glikman, Ilkka Mäkinen +1
In the present article, we review the classical covariant formulation of Yang-Mills theory and general relativity in the presence of spacetime boundaries, focusing mainly on the de…
Consistent first order action functional for gauge theories
Priidik Gallagher, Tomi S. Koivisto, Luca Marzola +2
A novel first order action principle has been proposed as the possible foundation for a more fundamental theory of General Relativity and the Standard Model. It is shown in this ar…
Cornering Quantum Gravity
Luca Ciambelli, Alessandra D'Alise, Vittorio D'Esposito +3
After introducing the covariant phase space calculus, Noether's theorems are discussed, with particular emphasis on Noether's second theorem and the role of gauge symmetries. This…
