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--GarcÃa 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--GarcÃa (ABG) massive black hole with graviton mass and magnetic charge. The Gibbs…
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…
Exploring non-perturbative effects on quasi-topological black hole thermodynamics
Vivek Kumar Srivastava, Sudhaker Upadhyay, Alok Kumar Verma +3
We examine the impact of non-perturbative quantum corrections to the entropy of both charged and charged rotating quasi-topological black holes, with a focus on their thermodynamic…
Impact of Perfect Fluid Dark Matter on the Thermodynamics of Ayón--Beato--GarcÃa Black Holes
Amit Kumar, Dharm Veer Singh, Sudhaker Upadhyay
In this paper, we derive the black hole solution in the context of nonlinear electrodynamics (NLED) coupled to a perfect fluid dark matter (PFDM) field. The resulting black hole so…
Ayón--Beato--GarcÃa black hole coupled with a cloud of strings: thermodynamics, shadows and quasinormal modes
Amit Kumar, Dharm Veer Singh, Sudhaker Upadhyay
We find an exact black hole solution for the Einstein gravity in the presence of Ayón--Beato--GarcÃa non-linear electrodynamics and a cloud of strings. The resulting black hole s…
