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.

    • ‘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.’

    • ‘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.’
    • ‘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.’
    • ‘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.’
    • ‘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.’
