In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. [1] : xi QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles .
22. Juni 2006 · Quantum Field Theory (QFT) is the mathematical and conceptual framework for contemporary elementary particle physics. It is also a framework used in other areas of theoretical physics, such as condensed matter physics and statistical mechanics.
L. Ryder, Quantum Field Theory This elementary text has a nice discussion of much of the material in this course. A. Zee, Quantum Field Theory in a Nutshell This is charming book, where emphasis is placed on physical understanding and the author isn’t afraid to hide the ugly truth when necessary. It contains many gems. M Srednicki, Quantum ...
quantum field theory, body of physical principles combining the elements of quantum mechanics with those of relativity to explain the behaviour of subatomic particles and their interactions via a variety of force fields.

A modern, accessible, inclusive, first principles introduction to quantum field theory. Provides a basic working knowledge of field theory, functional methods and Feynman diagrams. Introduces renormalization, the renormalization group and the basics of quantum electrodynamics.
In these lectures we present a few topics in Quantum Field Theory in detail. Some of them are conceptual and some more practical. They have been selected because they appear frequently in current applications to Particle Physics and String Theory. ∗Based on lectures delivered by L.A.-G. at the 3rd. CERN-CLAFSchool of High-Energy Physics ...
Although there was no unique and fully developed theory, quantum field theoretical tools could be applied to concrete processes. Examples are the scattering of radiation by free electrons (“Compton scattering”), the collision between relativistic electrons or the production of electron-positron pairs by photons.
Highlights: Theoretical methods are motivated and validated with concrete physical questions and experimental data. Numerous worked examples and end-of-chapter problems enable students to reproduce classic results and to master modern quantum field theory.
By Richard Webb. Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist...
