Quantum field theory — In quantum field theory (QFT) the forces between particles are mediated by other particles. For instance, the electromagnetic force between two electrons is caused by an exchange of photons. But quantum field theory applies to all fundamental… … Wikipedia
quantum field theory — Physics. any theory in which fields are treated by the methods of quantum mechanics; each field can then be regarded as consisting of particles of a particular kind, which may be created and annihilated. [1945 50] * * * Theory that brings quantum … Universalium

quantum field theory — The overall theory of fundamental particles and their interactions. Each type of particle is represented by appropriate operators which obey certain commutation laws. Particles are the quanta of fields in the same way as photons are the quanta of … Dictionary of automotive terms
Quantum field theory in curved spacetime — is an extension of standard quantum field theory to curved spacetime. A general prediction of this theory is that particles can be created by time dependent gravitational fields, or by time independent graviational fields that contain… … Wikipedia
quantum field theory — noun 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 • Hypernyms: ↑quantum physics • Hyponyms: ↑quantum… … Useful english dictionary
Noncommutative quantum field theory — In mathematical physics, noncommutative quantum field theory (or quantum field theory on noncommutative spacetime) is an application of noncommutative mathematics to the spacetime of quantum field theory that is an outgrowth of noncommutative… … Wikipedia
Topological quantum field theory — A topological quantum field theory (or topological field theory or TQFT) is a quantum field theory which computes topological invariants.Although TQFTs were invented by physicists (notably Edward Witten), they are primarily of mathematical… … Wikipedia
Constructive quantum field theory — In mathematical physics, constructive quantum field theory is the field devoted to showing that quantum theory is mathematically compatible with special relativity. This demonstration requires new mathematics, in a sense analogous to Newton… … Wikipedia
History of quantum field theory — The history of quantum field theory starts with its creation by Dirac when he attempted to quantize the electromagnetic field in the late 1920s. Foundations The early development of the field involved Fock, Pauli, Heisenberg, Bethe, Tomonaga,… … Wikipedia
