Localization properties of a QFT model, consisting of a quantum scalar field interacting linearly with a classical localized source, are investigated using various approaches present in the literature. We evaluate, to any order of the field–matter coupling constant, the time evolution of average values of one-point localization observables and scalar ...

This chapter presents the most important notions and examples of the theory of operator algebras. These are then used to formulate the basic principles of quantum field theory and some examples of algebraic QFTs.

As presaged in Chap. 1, we will primarily be interested in understanding entanglement in holographic field theories. But before we get to this particular set of quantum systems, it is useful to build some intuition in a more familiar setting. In this and the next section, we will therefore focus our attention on getting some insight into the concept of

AbstractThis chapter investigates the anomaly within standard mathematical techniques. It works predominantly in perturbation theory, calculating Feynman diagrams. It shows in detail the occurrence of the anomaly in quantum field theory (QFT) and discusses its meaning.
