Topology of thermodynamics in -charged black holes

NJ Gogoi, P Phukon - Physical Review D, 2023 - APS
We study the topology of black hole thermodynamics in four-, five-, and seven-dimensional
R-charged black holes. While the 4D R-charged black hole possesses four charges, the 5D …

[HTML][HTML] Thermodynamic topology of D= 4, 5 Horava Lifshitz black hole in two ensembles

B Hazarika, P Phukon - Nuclear Physics B, 2024 - Elsevier
In this paper, we investigate the thermodynamic topology of four and five-dimensional
Hořava-Lifshitz (HL) black holes within Hořava gravity. To analyze their thermodynamic …

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 …

Thermodynamic topology of 4D Euler–Heisenberg-AdS black hole in different ensembles

NJ Gogoi, P Phukon - Physics of the Dark Universe, 2024 - Elsevier
We study the thermodynamic topology of 4D Euler-Heisenberg-AdS (EHAdS) black hole and
higher-order QED corrected Euler-Heisenberg-AdS black hole in different ensembles using …

Geodesics in geometrothermodynamics (GTD) type II geometry of 4D asymptotically anti-de-Sitter black holes

NJ Gogoi, GK Mahanta, P Phukon - The European Physical Journal Plus, 2023 - Springer
In this work, we study the thermodynamic geodesics of 4D asymptotically anti-de Sitter black
holes in the context of the geometrothermodynamics (GTD) type II metric. We construct GTD …

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 …

Lyapunov exponents and phase transition of Hayward AdS black hole

NJ Gogoi, S Acharjee, P Phukon - The European Physical Journal C, 2024 - Springer
In this paper, we study the relationship between the phase transition and Lyapunov
exponents for 4D Hayward anti-de Sitter (AdS) black hole. We consider the motion of …

Stringy charged AdS5× S5 black holes shadows
