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…

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…
