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 .
Quantenfeldtheorie. Die Quantenfeldtheorie ( QFT) ist ein Gebiet der theoretischen Physik, in dem Prinzipien klassischer Feldtheorien (zum Beispiel der klassischen Elektrodynamik) und der Quantenmechanik zur Bildung einer erweiterten Theorie kombiniert werden. Sie geht über die Quantenmechanik hinaus, indem sie Teilchen und Felder ...
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 ...
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.
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. Two examples of modern quantum field theories are quantum electrodynamics, describing the interaction of electrically charged ...

22. Juni 2006 · Quantum Field Theory. Quantum Field Theory (QFT) is the mathematical and conceptual framework for contemporary elementary particle physics. Since the very beginning of western philosophy reflections about the material world which go beyond the directly observable play a central role in philosophy.
