Definition of quantum electrodynamics in US English:
quantum electrodynamics
plural noun
treated as singularA quantum field theory that deals with the electromagnetic field and its interaction with electrically charged particles.
‘The electromagnetic interaction is described by the theory of quantum electrodynamics, one of the most successful theories of physics.’
‘Here is the great American physicist Richard Feynman describing the success of quantum electrodynamics.’
‘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.’
‘At the heart of these experiments is the Casimir effect, a phenomenon from quantum electrodynamics.’
‘Usually, though, the credit for inspiring nanotechnology goes to a lecture by Richard Phillips Feynman, a brilliant Caltech physicist who later won a Nobel Prize for ‘fundamental work in quantum electrodynamics.’’
‘For this reason physicists sought the quantum theory of electromagnetism or quantum electrodynamics.’
‘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.’
‘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‘.’
‘The marvelous theory of electrons and their interactions with light is called quantum electrodynamics, or QED.’
‘Experiments on the hyperfine structure of hydrogen-like ions of heavy elements also require knowing the Bohr-Weisskopf effect in order to extract the influence of quantum electrodynamics.’
‘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.’
‘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.’
‘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.’
‘Dick said that this was the only piece of research on quantum electrodynamics that came as a surprise to him.’
‘This is nowhere more obvious than in quantum electrodynamics which is the most accurate theory in the history of science so far.’
‘There are the laws of quantum electrodynamics, which control the basic atomic and subatomic structure of all the components of my personal computer's electronics.’
‘There was only one talk about physics itself, a brief tutorial on quantum electrodynamics by Joe Polchinski.’
‘But this reconciliation has been carried out successfully, in the theory of quantum electrodynamics, which glories in the auspicious acronym of QED.’
‘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.’
