Celestial Holography, A Hitchhiker's Guide to the Celestial Sphere
Faïçal Barzi
This primer offers an first introduction to Celestial Holography, a rapidly evolving framework aiming to describe quantum gravity in asymptotically flat spacetimes. We start from t…
Accretion and Neutrino-Motivated Thermal Diagnostics of Thermodynamically Reconstructed Black Holes from Three-Parameter Generalized Entropy
F. Barzi, W. El Hadri, H. El Moumni +2
We study accretion and thermal diagnostics motivated by neutrino processes for a static black hole reconstructed from a three-parameter generalized entropy. The construction is the…
Modified Unruh Thermodynamics in Emergent Gravity: Finite Heat Capacity and Rényi Entropy
F. Barzi, H. El Moumni, K. Masmar
We show that Jacobson's thermodynamic derivation of Einstein's equations remains valid when local Rindler horizons are treated as finite heat-capacity systems, resolving the unphys…
On Rényi Microstructural Aspects of Asymptotically Flat Charged Black Holes: A Novel Duality
F. Barzi, H. El Moumni, K. Masmar
We explore the microstructure of asymptotically flat charged black holes through the lens of nonextensive Rényi statistics. A modified form of the Rényi entropy is proposed to inco…
Nonextensive Black Hole Thermodynamics from Generalized Euclidean Path Integral and Wick's Rotation
F. Barzi, H. El Moumni, K. Masmar
This paper extends the Euclidean path integral formalism to account for nonextensive statistical mechanics. Concretely, we introduce a generalized Wick's rotation from real time $t…
Reformulation of Classical Thermodynamics from Information Theory
Faical Barzi, Kaoutar Fethi
In this study, we present a reformulation of classical equilibrium thermodynamics by replacing the obscure and ambiguous concept of entropy with the clear and intuitive concept of…
Riemann Surfaces and Winding Numbers of Rényi Phase Structure of Charged-Flat Black Holes
F. Barzi, H. El Moumni, K. Masmar
It's widely recognized that the free energy landscape captures the essentials of thermodynamic phase transitions. In this work, we extend the findings of [1] by incorporating the n…
Thermal chaos of charged-flat black hole via Rényi formalism
F. Barzi, H. El Moumni, K. Masmar
Charged-flat black holes in the Rényi extended phase space demonstrate phase structures akin to those of a van der Waals fluid in four-dimensional spacetime and mirror the behavior…
Rényi Topology of Charged-flat Black Hole: Hawking-Page and Van-der-Waals Phase Transitions
F. Barzi, H. El Moumni, K. Masmar
In this paper, we extend the proposed setup in [1,2] for finding the topological charges associated with the Hawking-Page and Van-der-Waals transition points as well as equilibrium…
On some phase equilibrium features of charged black holes in flat spacetime via Rényi statistics
F. Barzi, H. El Moumni, K. Masmar
Motivated by the nonextensive nature of entropy in gravitational context and the Gauge/Gravity duality, black hole thermodynamics has been attracting intense emphasis in the litera…
On Rényi universality formula of charged flat black holes from Hawking-Page phase transition
Faical Barzi, Hasan El Moumni
Probing the thermodynamic properties of the Hawking-Page phase transition of asymptotically-flat black holes in Rényi statistics. We reveal the evidence for the persisting of the d…
On Complex numbers in Quantum Mechanics
Faical Barzi
We look at the fundamental use of complex numbers in Quantum Mechanics (QM). A review of some of the most popular reasons given in the literature to support the necessity of the co…
A look into the possibility of negative mass
Faical Barzi
We investigate the possibility of negative mass particles and whether physics as we know it today allows or excludes their existence and what properties they might have in the ligh…
