   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 ...

     Tracing the history of perturbative expansion in quantum field theory

     Perturbative expansion is a valuable mathematical technique which is widely used to break down descriptions of complex quantum systems into simpler, more manageable parts. Perhaps most importantly, it has enabled the development of quantum field theory (QFT): a theoretical framework that combines principles from classical,

    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.
