quantum field theory

n.
The application of quantum mechanics to physical systems described by fields, such as electromagnetic fields, developed to make quantum mechanics both consistent with the theory of special relativity and more readily applicable to systems involving many particles or the creation and destruction of particles.

quantum field theory

n
(Atomic Physics) physics quantum mechanical theory concerned with elementary particles, which are represented by fields whose normal modes of oscillation are quantized
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.quantum field theory - the branch of quantum physics that is concerned with the theory of fields; it was motivated by the question of how an atom radiates light as its electrons jump from excited states
quantum physics - the branch of physics based on quantum theory
QED, quantum electrodynamics - a relativistic quantum theory of the electromagnetic interactions of photons and electrons and muons
QCD, quantum chromodynamics - a theory of strong interactions between elementary particles (including the interaction that binds protons and neutrons in the nucleus); it assumes that strongly interacting particles (hadrons) are made of quarks and that gluons bind the quarks together
