Abstract

This project aims to study the mathematical and conceptual foundations of quantum field theory in curved spacetimes. The research plan consists mainly on a review of the literature. However, depending on its progress we will do a small original analysis at the end. We will focus on the quantization of free scalar fields on globally hyperbolic spacetimes and its various consequences in the context of black holes. After studying the general formalism, we will apply it to the case where the field propagates in a spacetime which describes the complete gravitational collapse of a star producing a black hole. This will lead us to the Hawking effect and then we will to study its various aspects. At the end, we hope not only to give a sound background in semiclassical gravity to the student but also take her to the edge of an extremely interesting and active field which still reserves many striking results (especially related to thermodynamic aspects of black holes and the fate of information in its evaporation process).
