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…
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…
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…
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 Carrollian and Galilean contractions of BMS algebra in 3 and 4 dimensions
Andrzej Borowiec, Jerzy Kowalski-Glikman, Tomasz Trześniewski
In this paper, we find a class of Carrollian and Galilean contractions of (extended) BMS algebra in 3+1 and 2+1 dimensions. To this end, we investigate possible embeddings of 3D/4D…
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…
On symmetries and charges at spatial infinity
L. Brocki, J. Kowalski-Glikman
Following the recent work of Henneaux and Troessaert, which revisits the problem of spacetime symmetries at spatial infinity, we analyze this problem using the Bondi metric without…
Local Maxwell symmetry and gravity
R. Durka, J. Kowalski-Glikman
In this paper we discuss some physical aspects of a theory obtained by gauging the AdS-Maxwell symmetry. Such theory has the form of Einstein gravity coupled to the …
AdS--Maxwell superalgebra and supergravity
R. Durka, J. Kowalski-Glikman, M. Szczachor
In this paper we derive the Anti de Sitter counterpart of the super-Maxwell algebra presented recently by Bonanos et.\ al. Then we gauge this algebra and derive the corresponding s…
Hamiltonian analysis of SO(4,1) constrained BF theory
R. Durka, J. Kowalski-Glikman
In this paper we discuss canonical analysis of SO(4,1) constrained BF theory. The action of this theory contains topological terms appended by a term that breaks the gauge symmetry…
Doubly special quantum and statistical mechanics from quantum -Poincaré algebra
J. Kowalski-Glikman
Recently Amelino--Camelia proposed a ``Doubly Special Relativity'' theory with two observer independent scales (of speed and mass) that could replace the standard Special Relativit…
Topological Black Holes in Quantum Gravity
J. Kowalski-Glikman, D. Nowak-Szczepaniak
We derive the black hole solutions with horizons of non-trivial topology and investigate their properties in the framework of an approach to quantum gravity being an extension of B…
The Time Evolution of Quantum Universe in The Quantum Potential Picture
A. Blaut, J. Kowalski-Glikman
We use the quantum potential approach to analyse the quantum cosmological model of the universe. The quantum potential arises from exact solutions of the full Wheeler-De Witt equat…
On the Gupta-Bleuler Quantization of the Hamiltonian Systems with Anomalies
J. Kowalski-Glikman
As compared to the previous version, the example of Gupta-Bleuler quantization of massive electrodynamics was added, and the derivation of path integral for anomalous theories is f…
