Generalized electrodynamics and field theory extend the classical Maxwell formulation by incorporating additional derivative terms, nonlocal interactions and modifications to gauge invariance. Such ...
Data gathered by a team at the National Institute of Standards and Technology (NSIT) suggest that certain aspects of the highly regarded quantum electrodynamics theory might require some revising.
Classical field theory is a research area in theoretical physics that studies continuous fields, such as electromagnetic, gravitational, and scalar fields, within a pre-quantum, typically relativistic ...
A quantum theory of electrodynamics is shown to be accurate even at the very high electric fields of exotic atoms By creating special atoms, RIKEN physicists have tested what happens to quantum ...
To put one of physicists’ most important theories to the test, scientists go to extremes. Extremely strong electromagnetic fields, that is. The theory of quantum electrodynamics, which describes ...
For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has been a cornerstone of the standard model, withstanding the scrutiny of ...
Quantum field theory is notoriously complicated, built from mind-bendingly abstract mathematics. But are the underlying rules of reality really so far from human intuition? Or are physicists just ...
Science News: A pivotal quantum theory holds up even in extreme electric fields
Classical field theories provide a framework for describing fundamental interactions and physical phenomena through the use of continuous fields defined over space and time. Central to these theories ...
Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, ...
