Entropy bounds, Geroch process, and the sign of deformation parameter
Bijan Bagchi, Akshat Pandey, Parmest Roy +1
Based on Geroch's process of dropping a system into a black hole from the vicinity of the horizon, we investigate in this paper the influence of deformation on the Bekenstein entro…
Dimming of Photon Ring due to Photon-Axion Conversion around Kerr Black Holes
Rahul Dhyani, Sauvik Sen, Indrani Banerjee +2
We investigate photon-axion conversion in the vicinity of rotating Kerr black holes where strong gravity traps photons on near-circular trajectories, effectively enhancing the path…
Painlevé-Gullstrand coordinates for Kiselev black holes
Bijan Bagchi, Sauvik Sen
We investigate the implications provided by the modified Painlevé-Gullstrand coordinates in the context of quintessence for the Kiselev black hole. In this regard, we set up a full…
Quantum tunneling driven by quintessence and the role of GUP
Sauvik Sen
In this paper, we studied quantum tunneling of massless and massive particles pertaining to a Schwarzschild black hole in a quintessence background, and explored the consequences e…
Quantized Area of the Schwarzschild Black Hole: A non-Hermitian Perspective
Bijan Bagchi, Aritra Ghosh, Sauvik Sen
In this work, our aim is to link Bekenstein's quantized form of the area of the event horizon to the Hamiltonian of the non-Hermitian Swanson oscillator which is known to be $\math…
Landauer's principle and black hole area quantization
Bijan Bagchi, Aritra Ghosh, Sauvik Sen
This article assesses Landauer's principle from information theory in the context of area quantization of the Schwarzschild black hole. Within a quantum-mechanical perspective wher…
