Is quantum electrodynamics complete?

QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction.

Why is it called quantum chromodynamics?

The force between quarks is known as the colour force (or color force) or strong interaction, and is responsible for the nuclear force. Since the theory of electric charge is dubbed “electrodynamics”, the Greek word χρῶμα chroma “color” is applied to the theory of color charge, “chromodynamics”.

What is quantum electrodynamics in physics?

In particle physics, quantum electrodynamics ( QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved.

Is it possible to get fully covariant quantum electrodynamics?

Based on Bethe’s intuition and fundamental papers on the subject by Shin’ichirō Tomonaga, Julian Schwinger, Richard Feynman and Freeman Dyson, it was finally possible to get fully covariant formulations that were finite at any order in a perturbation series of quantum electrodynamics.

What is the history of quantum chromodynamics?

QED has served as the model and template for all subsequent quantum field theories. One such subsequent theory is quantum chromodynamics, which began in the early 1960s and attained its present form in the 1970s work by H. David Politzer, Sidney Coleman, David Gross and Frank Wilczek.

What is the field theory of quantum mechanics?

Quantum field theory. History. In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved.
