Dark Matter Signatures in Black Hole Thermodynamics and Information Recovery
Yahya Ladghami, Brahim Asfour, Taoufik Ouali
In this paper, we investigate the thermodynamic properties and information recovery of Schwarzschild and Reissner--Nordstr"om black holes surrounded by perfect fluid dark matter. W…
Thermodynamics and information recovery of Schwarzschild AdS black holes in conformal Killing gravity
Yahya Ladghami, Brahim Asfour, Francisco S. N. Lobo +1
We study Schwarzschild AdS black holes in conformal Killing gravity, focusing on their thermodynamics and information recovery via the island formula. Treating the cosmological con…
Gravitational waves production during preheating within GB gravity with monomial coupling
Brahim Asfour, Yahya Ladghami, Taoufik Ouali
In this paper, we investigate the production of gravitational waves during the preheating era. To achieve this purpose, we consider Gauss-Bonnet inflation model with Power{\textend…
Timelike Entanglement Entropy of Hawking Radiation
Yahya Ladghami, Francisco S. N. Lobo, Taoufik Ouali
We introduce the concept of timelike entanglement entropy of Hawking radiation as a novel probe of the black hole information paradox. By analytically continuing black hole spaceti…
Holographic Central Charge Effects on Black Hole Thermodynamics and Quantum Information
Yahya Ladghami, Taoufik Ouali
In this paper, based on the Anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence, we highlight the fundamental role of the holographic central charge in connecting the bo…
Primordial black holes within Higgs hybrid metric-Palatini approach
Brahim Asfour, Farida Bargach, Yahya Ladghami +2
In this paper, we investigate the production of primordial black holes (PBHs) during the radiation-dominated era. The collapse of significant density perturbations originating from…
