Forward modelling coronagraphic images with a fully physical, differentiable digital twin of MagAO-X: first laboratory results
Matthijs Mars, Sebastiaan Y. Haffert, Louis Desdoigts +10
Post-processing of high contrast imaging data relies on an accurate model of the stellar point spread function (PSF). Current techniques build this model from the science images th…
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
In this manuscript, we propose a novel topological framework based on the heat capacity of black holes to investigate the topology of thermodynamic multicritical points. We constru…
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…
Critical slowing down of black hole phase transition and universal dynamic scaling in AdS black holes
Mozib Bin Awal, Prabwal Phukon
We investigate the dynamical critical behaviour of black hole phase transitions in anti de Sitter spacetime by extending the stochastic framework of free energy landscape dynamics…
Phase Transitions and Chaos Bound in Horava Lifshitz Black Holes using Lyapunov Exponents
Mozib Bin Awal, Prabwal Phukon
We probe the thermodynamic phase structure of four dimensional Horava Lifshitz black holes by Lyapunov exponent analysis. For both massless and massive test particles, the Lyapunov…
Testing the AdS/CFT Correspondence Through Thermodynamic Geometry of Nonlinear Electrodynamics AdS Black Holes with Generalized Entropies
Abhishek Baruah, Amijit Bhattacharjee, Prabwal Jyoti Phukon
We investigate the thermodynamics and thermodynamic geometry of several Anti--de Sitter black hole solutions arising from nonlinear electromagnetic theories, namely the ModMax, non…
Information-Geometric Signatures from Nonextensivity in the -D Blume-Capel Model
Amijit Bhattacharjee, Himanshu Bora, Prabwal Phukon
We study the thermodynamic geometry of the one-dimensional Blume--Capel model within the Tsallis nonextensive framework to understand how generalized statistics modify correlation…
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…
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…
