A Note on Vacuum Polarisation and Hawking Radiation
Arundhati Dasgupta, Shohreh Rahmati
We re-examine vacuum polarisation of a scalar field in a quasi-local volume including the horizon. We find that Hawking radiation rate is derived as a pure decay of vacuum due to s…

Semiclassical Loop Quantum Gravity and Black Hole Thermodynamics
Arundhati Dasgupta
In this article we explore the origin of black hole thermodynamics using semiclassical states in loop quantum gravity. We re-examine the case of entropy using a density matrix for…

Time Evolution of Horizons
Arundhati Dasgupta
A density matrix is defined using coherent states for space-times with apparent horizons. Evolving the density matrix in time gives the origin of Hawking radiation.
