Charged Black Holes in Einstein-- Gravity with Letelier--Alencar Cloud of Strings: Thermodynamics and QPO-Based Observational Constraints
B. Eslam Panah, Bidyut Hazarika, Prabwal Phukon
In this study, black hole solutions are derived within the framework of Einstein gravity, coupled to a gauge field in the presence of both the Letelier--Alencar \textit{clou…
Brouwer Degree of Thermodynamic Multicritical Points in Black Holes
Bidyut Hazarika, Prabwal Phukon
The paper introduces a topological framework based on black hole heat capacity, constructing a thermodynamic vector field whose zeros identify critical points and assigning each a…
Degenerate Bifurcations and Universal Relaxation Scaling in Black Hole Thermodynamics
Bidyut Hazarika, Mozib Bin Awal, Prabwal Phukon
We present a dynamical systems approach to black hole thermodynamic criticality based on bifurcation equations. We construct an effective thermodynamic landscape in which black hol…
Probing Black Hole Phase Transitions through Quasi-Periodic Oscillations
Bidyut Hazarika, Prabwal Phukon
In this work, we probe the well known thermodynamic phase structure of black hole through the lens of its quasi-periodic oscillations (QPOs). Can QPOs be influenced by black hole p…
Quasi-Periodic Oscillations and Parameter Constraints in ModMax Black Holes
Mozib Bin Awal, Bidyut Hazarika, Prabwal Phukon
We analyze the impact of ModMax parameter on the dynamics of test particles around black holes and its effect on the characteristics of Quasi-Periodic Oscillations (QPOs). The effe…
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…
