Definition of quantum field theory in English: quantum field theorynoun Physics A field theory that incorporates quantum mechanics and the principles of the theory of relativity. Example sentencesExamples - He worked on atomic collisions, astrophysics, low-temperature physics, atomic and nuclear physics, thermodynamics, quantum electrodynamics, kinetic theory of gases, quantum field theory, and plasma physics.
- Quantum electrodynamics, and its expansion to the electroweak Standard Model of particle physics, is also a quantum field theory.
- Black hole radiation, known as Hawking radiation, comes about because relativistic quantum field theory is invariant under Lorentz transformations, but not under general coordinate transformations.
- Physicists originally had a lot of trouble reconciling relativistic quantum field theory with the weak interaction that is responsible, for example, for what is called beta decay of neutron into proton, electron and neutrino.
- In quantum field theory, the behaviors and properties of elementary particles can calculated using a series of diagrams, called Feynman diagrams, that properly account for the creation and annihilation of virtual particles.
