Selective enhancement of quantum decay channels

Pritam Nanda, Kinjalk Lochan

In the decay of quantum particles under field theoretic consideration, the decay rate is typically a convolution of the density of modes the primary field is allowed to decay into…

Microstate Counting for rotating (type~II) isolated horizons

Pritam Nanda

We present a proposal for black hole microstate counting in Loop Quantum Gravity (LQG) for rotating (type~II) isolated horizons. The key obstacle in extending the standard nonrotat…

Hawking temperature of black holes with multiple horizons

Chiranjeeb Singha, Pritam Nanda, Pabitra Tripathy

There are several well-established methods for computing thermodynamics in single-horizon spacetimes. However, understanding thermodynamics becomes particularly important when deal…

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 in multi-horizon spacetimes using Hamilton Jacobi method

Chiranjeeb Singha, Pritam Nanda, Pabitra Tripathy

It has been recently shown that the contribution between the horizons determines the Hawking temperature for a multi-horizon spacetime. In this article, we apply the Hamiltonian Ja…

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…

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…
