unified field theory — n. Physics any theory that attempts to explain two or more field theories using one set of mathematical laws, as in the unification of the field theories of magnetism and electricity: see GRAND UNIFIED (FIELD) THEORY … English World dictionary
Unified field theory — In physics, a unified field theory is a type of field theory that allows all of the fundamental forces between elementary particles to be written in terms of a single field. There is no accepted unified field theory yet, and this remains an open… … Wikipedia
unified field theory — Physics. 1. See electroweak theory. 2. any field theory, esp. Einstein s, that attempts to combine the gravitational and electromagnetic fields in a single mathematical framework, thus extending the general theory of relativity. * * * Attempt to… … Universalium
grand unified theory — or grand unification theory (GUT) Theory that attempts to unify the electroweak force (see electroweak theory) with the strong force. The unification of all four fundamental interactions is sometimes called unified field theory. Such theories… … Universalium

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 — 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
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
