Null-Energy Bounds on Photon-Orbit Instability in Einstein-Gauss-Bonnet Gravity
Sarandas A., C. Fairoos, C. L. Ahmed Rizwan
We derive a local upper bound on the coordinate-time Lyapunov exponent of unstable circular null orbits in static, spherically symmetric, asymptotically flat Einstein--Gauss--Bonne…
Bounds on the Lyapunov Exponent of Circular Null Orbits in -Dimensional Black-Hole Spacetimes
Anagha V., C. Fairoos, T. K. Safir
Unstable circular null orbits provide a geometric bridge between black-hole optics, photon rings, strong gravitational lensing, and the eikonal sector of quasinormal ringing. In fo…
Thermodynamics of Einstein-Gauss-Bonnet Black Holes under the Generalized Uncertainty Principle
Sasmita Kumari Pradhan, Jamima Gee Varghese, C. Fairoos
We explore the impact of the Generalized Uncertainty Principle (GUP) on the thermodynamics of five-dimensional Einstein-Gauss-Bonnet (EGB) black holes. A modified mass-temperature…
From Nonextremal to Extremal: Entropy of Reissner-Nordström and Kerr black holes Revisited
C. Fairoos, Chiranjeeb Singha
In this paper, we derive the entropy of Reissner-Nordström (RN) and Kerr black holes using the Hawking-Gibbons path integral method. We determine the periodicity of the Euclidean t…
Phase-space Path Integral Approach to the Kinetics of Black Hole Phase Transition in Massive Gravity
C. Fairoos, T. K. Safir, Deepak Mishra
The dynamics of the state-switching process of black holes in dRGT massive gravity theory is presented using free energy landscape and stochastic Langevin equations. The free energ…
Topological Interpretation of Black Hole Phase Transition in Gauss-Bonnet Gravity
C. Fairoos
Phase transitions of Einstein-Gauss-Bonnet black holes are studied using Duan's field topological current theory, where black holes are treated as topological defects in the t…
Physical Process First Law and the Entropy Change of Rindler Horizons
T. K. Safir, C. Fairoos, Deepak Vaid
The physical process version of the first law can be obtained for bifurcate Killing horizons with certain assumptions. Especially, one has to restrict to the situations where the h…
Dynamic Phase Transition of Black Holes in Massive Gravity
T. K. Safir, A. Naveena Kumara, Shreyas Punacha +3
The dynamical properties of small-large black hole phase transition in dRGT non-linear massive gravity theory are studied based on the underlying free energy landscape. The free en…
Topological Nature of Black Hole Solutions in dRGT Massive Gravity
C. Fairoos, T. Sharqui
We study the thermodynamic properties of black holes in dRGT massive gravity theory using Duan's topological current mapping theory. The topological features and the correspon…
Overcharging higher curvature black holes
Rajes Ghosh, C. Fairoos, Sudipta Sarkar
We examine the problem of overcharging extremal and near-extremal black hole solutions of Einstein-Gauss-Bonnet gravity in any dimension, generalizing the result in general relativ…
Boundary Conservation from Bulk Symmetry
C. Fairoos, Avirup Ghosh, Sudipta Sarkar
The evolution of the black hole horizon can be effectively captured by a fictitious membrane fluid living on the stretched horizon. We show that the dynamics of this boundary matte…
Black Hole Entropy production and Transport coefficients in Lovelock Gravity
C. Fairoos, Avirup Ghosh, Sudipta Sarkar
We study the entropy evolution of black holes in Lovelock gravity by formulating a thermodynamic generalization of null Raychaudhuri equation. We show that the similarity between t…
Massless charged particles: Cosmic censorship, and Third law of Black Hole Mechanics
C. Fairoos, Avirup Ghosh, Sudipta Sarkar
The formulation of the laws of black hole mechanics assumes the stability of black holes under perturbations in accordance with the "cosmic censorship hypothesis"(CCH). CCH prohibi…
Higher curvature self-interaction corrections to Hawking Radiation
C. Fairoos, Sudipta Sarkar, K. P. Yogendran
The purely thermal nature of Hawking radiation from evaporating black holes leads to the information loss paradox. A possible route to its resolution could be if (enough) correlati…
