Entanglement Islands, Page curves and Phase Transitions of Kerr-AdS Black Holes
Digen Das, Mozib Bin Awal, Prabwal Phukon
We study the Page curve and information paradox for Kerr AdS black hole in light of entanglement entropy by employing the recently proposed island paradigm. By incorporating the is…
Bifurcation and Critical Phenomena in Black Hole Thermodynamics
Bidyut Hazarika, Prabwal Phukon
In this work, we treat black holes as bifurcation points and explore their thermodynamic phase structure using the framework of bifurcation theory which is a commonly used method f…
Investigating Optical and Ring-Down Gravitational Wave Properties of a Rotating Black Hole in a Dehnen Galactic Dark Matter Halo
Mrinnoy M. Gohain, Dhruba Jyoti Gogoi, Kalyan Bhuyan +1
We present a comprehensive study of the optical and dynamical properties of a rotating black hole immersed in a Dehnen-type galactic dark matter halo, modeled by a double…
Observational Constraints on f(R,T) gravity coupled with NED from Black Hole Quasi Periodic Oscillations
Bidyut Hazarika, Abhishek Baruah, Prabwal Phukon
In this work, we examine the influence of nonlinear electrodynamics (NED) and gravity on quasi-periodic oscillations (QPOs) around a magnetically charged black hole. By an…
Lyapunov Exponents, Phase Transitions, and Chaos Bound of ModMax AdS Black Holes
Gorima Bezboruah, Mozib Bin Awal, Prabwal Phukon
We study the thermodynamic phase transition of ModMax anti-de Sitter (AdS) black holes using Lyapunov exponents of massless and massive particles in unstable circular orbits. Our r…
Holographic Fractional Order Phase Transitions in CFTs Dual to AdS Black Holes
Abhishek Baruah, Prabwal Phukon
In this work, we investigate the CFT phase transitions of various AdS black hole solutions, including the Reissner-Nordström-AdS (RN-AdS) black hole, the ModMax-AdS black hole, and…
