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…
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…
Charges of supergravity
Remigiusz Durka, Jerzy Kowalski-Glikman, Rene Payne
We study conserved charges of supergravity formulated as a constrained BF theory based on the $\OSp(1|4)$ superalgebra. Using the covariant phase space formalism, w…
On the non-commutativity of geometric observables in different Lorentz frames
Mehdi Assanioussi, Jerzy Kowalski-Glikman, Ilkka Mäkinen +1
Our aim is to establish whether geometric observables, such as length, area or volume of a physical object, viewed by different observers Poisson commute or not. To illustrate this…
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…
