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…
BMS transformed Quantum String Dynamics near a Black Hole
Nihar Ranjan Ghosh, Malay K. Nandy
Asymptotic symmetries are expected to leave subtle but physically meaningful imprints on quantum probes of gravity, yet their manifestation in near-horizon dynamics remains incompl…
Constraints on BMS Transformations via Energy Conditions and implications on black hole geometry
Nihar Ranjan Ghosh, Malay K. Nandy
We investigate whether the formally infinite-dimensional supertranslation sector of the Bondi-Metzner-Sachs (BMS) group remains fully physically admissible once classical energy co…
Asymptotic Generation of Kerr Geometry from Schwarzschild via BMS Supertranslations
Nihar Ranjan Ghosh, Malay K. Nandy
The Bondi-van der Burg-Metzner-Sachs (BMS) group, as the asymptotic symmetry group of asymptotically flat spacetimes, plays a central role in connecting infrared structures of grav…
Nonlinear Dynamics of the Inner Horizon in Reissner-Nordström Black Holes: Insights into Mass Inflation
Nihar Ranjan Ghosh, Malay K. Nandy
The well-known instability of the inner horizon of a Reissner-Nordström black hole, first suggested by Simpson and Penrose, although studied extensively, has remained illusive so f…
