Definition of quantum electrodynamics in English:
quantum electrodynamics
plural noun
[treated as singular] A quantum field theory that deals with the electromagnetic field and its interaction with electrically charged particles.
- ‘The marvelous theory of electrons and their interactions with light is called quantum electrodynamics, or QED.’
- ‘But this reconciliation has been carried out successfully, in the theory of quantum electrodynamics, which glories in the auspicious acronym of QED.’
- ‘The electromagnetic interaction is described by the theory of quantum electrodynamics, one of the most successful theories of physics.’
- ‘At the heart of these experiments is the Casimir effect, a phenomenon from quantum electrodynamics.’
- ‘In his 1970 classic work The Feynman Lectures on Physics, Feynman covered all of physics - from celestial mechanics to quantum electrodynamics - with only two levels of hierarchy.’
- ‘There was only one talk about physics itself, a brief tutorial on quantum electrodynamics by Joe Polchinski.’
- ‘Dick said that this was the only piece of research on quantum electrodynamics that came as a surprise to him.’
- ‘In 1951 he proposed, what is today called the Schwinger effect in quantum electrodynamics, where electron-positron pairs are sucked out of a vacuum by an electric field.’
- ‘This is nowhere more obvious than in quantum electrodynamics which is the most accurate theory in the history of science so far.’
- ‘Freeman Dyson, a cofounder of quantum electrodynamics, explains what the theorem proves, namely that, ‘no finite set of axioms and rules of inference can ever encompass the whole of mathematics.’
- ‘Further understanding led to the development of relativistic quantum field theory, beginning with quantum electrodynamics, or QED for short, pioneered by Feynman, Schwinger and Tomonaga in the 1940s.’
- ‘Because of its similarity to quantum electrodynamics, and the theory of the nuclear weak force, QCD hinted that there might be a common explanation underlying all three forces.’
- ‘Paul Dirac famously remarked that with the advent of quantum electrodynamics we had in our hands a theory that covered ‘all of chemistry, and most of physics‘.’
- ‘How well verified is the theory of quantum electrodynamics?’
- ‘Methods for accurately calculating g were devised in the 1940s as part of a thorough overhaul of the theory of electrons - a theory called quantum electrodynamics, or QED.’
