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…
On Accretion and Neutrino Investigations of Thermodynamically Reconstructed Black Holes from Three-Parameter Generalized Entropy
F. Barzi, W. El Hadri, H. El Moumni +2
We study accretion and neutrino-sensitive thermal signatures of a static black hole reconstructed from a three-parameter generalized entropy. The construction is thermodynamic by d…
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 in…
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…
