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…
Dynamical Timelike Entanglement Entropy in an Evaporating Schwarzschild--AdS Black Hole
Digen Das, Prabwal Phukon
Timelike entanglement entropy (tEE) has recently emerged as a novel probe of temporal quantum correlations in gravitational systems. Existing studies are largely restricted to stat…
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…
Nonperturbative Isentropic Processes in AdS Black Holes with Nonlinear Electrodynamics
Mozib Bin Awal, Prabwal Phukon
We study the isentropic processes in a class of Anti de Sitter black holes coupled to non-linear electrodynamics. We demonstrate that such processes are classically forbidden but c…
Complex Phase Structure and Widom line for Euler Heisenberg black holes
Mozib Bin Awal, Prabwal Phukon
We investigate the supercritical thermodynamics of Euler-Heisenberg AdS black holes within the framework of Lee-Yang phase transition theory. We show that the system admits two dis…
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…
