Revisiting thermodynamic topology of Hawking-Page and Davies type phase transitions

B Hazarika, NJ Gogoi, P Phukon - Journal of High Energy Astrophysics, 2025 - Elsevier
In this work, we propose a common vector field to study the thermodynamic topology of the
Davies type and Hawking-Page phase transitions. Existing literature has shown that …

criticality of logarithm-corrected dyonic charged AdS black holes

J Sadeghi, B Pourhassan, M Rostami - Physical Review D, 2016 - APS
In this paper, we consider a dyonic charged anti-de Sitter black hole, which is a holographic
dual of a van der Waals fluid. We use logarithm-corrected entropy and study …

Thermodynamic topology of black holes in f (R) gravity

B Hazarika, P Phukon - Progress of Theoretical and …, 2024 - academic.oup.com
In this work, we study the thermodynamic topology of a static, a charged static, and a
charged rotating black hole in f (R) gravity. For charged static black holes, we work in two …

to the microcanonical entropy resulting due to thermodynamic fluctuations which are …

The Interconnection of Cosmological Constant and Renyi Entropy in Kalb-Ramond Black Holes: Insights from Thermodynamic Topology

B Hazarika, MB Awal, P Phukon - arXiv preprint arXiv:2412.09494, 2024 - arxiv.org
This paper seeks to establish a connection between the cosmological constant and Renyi
entropy within the framework of Kalb-Raymond (KR) gravity. Our analysis is supported by …

Logarithmic correction of the BTZ black hole and adaptive model of graphene

B Pourhassan, M Faizal, SA Ketabi - International Journal of Modern …, 2018 - World Scientific
It is known that almost all approaches to quantum gravity produce a logarithmic correction
term to the entropy of a black hole, but the exact coefficient of such a term varies between …

Thermodynamic Properties and Shadows of Black Holes in Gravity

B Hazarika, P Phukon - arXiv preprint arXiv:2410.00606, 2024 - arxiv.org
In this paper, we explore two $ f (R, T) $ gravity models and derive black hole solutions
within these models. We focus on investigating how the $ f (R, T) $ model influences the …
