Local first law of black hole
Pabitra Tripathy, Pritam Nanda, Amit Ghosh
We investigated the form and implications of the local first law of black hole thermodynamics in relation to an observer located at a finite distance from the black hole horizon. O…
Hawking radiation as quantum mechanical reflection
Pritam Nanda, Chiranjeeb Singha, Pabitra Tripathy +1
In this article, we explore an alternative derivation of Hawking radiation. Instead of the field-theoretic derivation, we have suggested a simpler calculation based on quantum mech…
Commutators in and Markoff surfaces I
Amit Ghosh, Chen Meiri, Peter Sarnak
We show that the commutator equation over satisfies a profinite local to global principle, while it can fail with infinitely many exceptions for $ \math…
Exponential corrections to black hole entropy
Ayan Chatterjee, Amit Ghosh
Using the quasilocal properties alone we show that the area spectrum of a black hole horizon must be discrete, independent of any specific quantum theory of gravity. The area spect…
Marginally Trapped Surfaces in Spherical Gravitational Collapse
Ayan Chatterjee, Amit Ghosh, Suresh Jaryal
This paper deals with a detail study of gravitational collapse of dust and viscous fluids under the assumptions of spherical symmetry. Our main goal is to closely analyze the horiz…
On Super-Translation transition between Quasi-local Black holes
Amit Ghosh, Avirup Ghosh, Pritam Nanda
We re-explore the symmetries of a weakly isolated horizon (WIH) from the perspective of freedom in the choice of intrinsic data. The supertranslations are realized as additional sy…
