TC3: Quantum Field Theory in Curved Spaces – Overview

  • Overview

Lecturer

Topic overview:

This lecture represents an elementary introduction to the tree-level theory of quantum fields on curved spacetimes. The essential structures relevant for a precise development are introduced at the level of classical mechanics and quantum mechanics. Once the level of presentation is sufficiently abstract, these concepts are lifted to infinite-dimensional Hamiltonian systems with a focus on massive scalar fields. Our approach to the corresponding quantum theory on globally hyperbolic backgrounds consists of two steps: In the first step the algebra of observables is constructed and studied, and in the second step a physical state concept is introduced in accordance with the usual interpretation of quantum systems. Finally the framework is applied to a thorough analysis of the so-called Unruh-effect and Hawking effect. If time permits an outlook beyond tree-level physics will be given.
