Quantum Cosmology in Page-Wootters' Framework: Singularity Resolution and Clock Coherence
Vishal, Malay K. Nandy
We investigate the fate of big-bang singularity and coherence between distinct clock states in a quantum cosmological setting within the Page-Wootters framework. With a canonically…
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…
Graceful Exit to Radiation Domination in the Starobinsky Model: A Dynamical Realization
Bhargabi Saha, Malay K. Nandy
The Starobinsky model provides a successful realization of inflation and serves as a benchmark for alternative inflationary models. Motivated by its observational success, we inves…
Dynamical Selection of Horizon-BMS Goldstone Modes in Evaporating Black Holes
Nihar Ranjan Ghosh, Malay K. Nandy
We investigate the dynamics of horizon soft degrees of freedom associated with near-horizon BMS supertranslations in an evaporating Vaidya-Schwarzschild black hole spacetime. Consi…
Near-Horizon BMS Symmetry and Implications on Black Hole Entropy
Nihar Ranjan Ghosh, Malay K. Nandy
Thermodynamic significance of near-horizon symmetries remains an important open question in black hole physics, particularly in the context of black hole evaporation and informatio…
Dynamical Baryogenesis in Rainbow Cosmology
Surendra Kumar Gour, Malay K. Nandy
We investigate baryogenesis in the framework of rainbow cosmology employing a complex scalar field with a softly broken global -symmetry. The modified dispersion relation of…
