Rényi Entropy and the Topological Features of Charged AdS Black Hole
Muhammad Yasir, Tong Lining, Farzan Mushtaq +4
This study applies Duan's topological current -mapping theory to investigate a newly proposed charged modified AdS black hole using the Rényi entropy formalism, examining its th…
Systematic Light Propagation Bias from the Heliosphere and Its Impact on the Hubble Tension
Behnam Pourhassan, İzzet Sakallı, Sudhaker Upadhyay +1
The Hubble tension (HT) represents one of the most significant discrepancies in modern cosmology, with local distance measurements yielding km/s/Mpc while cosm…
Perturbative and Non-Perturbative Contributions to Black Hole Thermodynamics with String Clouds and Dark Matter Backgrounds
Kumar Sambhav Upadhyay, Sudhaker Upadhyay, Bhabani Prasad Mandal
We investigate the effects of perturbative and non-perturbative quantum corrections on the thermodynamics of black holes immersed in a perfect fluid dark matter (PFDM) background w…
Extended thermodynamics and Criticality of Kalb-Ramond black hole coupled with nonlinear electrodynamics
D. V. Singh, S. Upadhyay, P. Paul +1
We present an exact black hole solution in anti-de Sitter (AdS) spacetime with a Kalb-Ramond field coupled to nonlinear electrodynamics (NLED), characterized by mass, magnetic mono…
Thermodynamics, Shadow, and Quasinormal Modes of AdS Ayón--Beato--García Massive Black Hole
Dharm Veer Singh, Sudhaker Upadhyay, Amit Kumar +3
We investigate the thermodynamics, photon sphere, and dynamical stability of an AdS Ayón--Beato--García (ABG) massive black hole with graviton mass and magnetic charge. The Gibbs f…
More Exact Thermodynamic Analysis of Topological Black Holes in Gravity
Sudhaker Upadhyay, Jyotish Kumar, Dharm Veer Singh +3
This study investigates the thermodynamics of topological black hole solutions in gravity, incorporating the effects of small statistical fluctuations up to first-order cor…
