Time Evolution of Horizons
Arundhati Dasgupta

TL;DR
This paper introduces a method to derive Hawking radiation by defining a density matrix with coherent states in space-times featuring apparent horizons and analyzing its time evolution.
Contribution
It presents a novel approach to understanding Hawking radiation through the evolution of a density matrix constructed from coherent states.
Findings
Derivation of Hawking radiation from density matrix evolution.
Insight into quantum state behavior near apparent horizons.
Potential implications for black hole thermodynamics.
Abstract
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.
