Probing the Black Hole Singularity with a Quantum String
Harpreet Singh, Malay K. Nandy
In this paper, we investigate the quantum behaviour near the classical singularity of a black hole. We describe the black-hole interior by the Kantowski-Sachs metric, with a string…

Trapped string states in AdS black hole geometry: A path toward Hawking radiation
Harpreet Singh, Malay K. Nandy
We investigate the quantum dynamics of a closed bosonic string in the curved spacetime of an AdS-Schwarzschild black hole. Starting from the Polyakov action, we perform a canon…
