As a teenager, he played in a rock band called QED, in which he, Cliff Ashcroft, Mark Fawl and Chris Swift wrote much of their own music and lyrics.

Unlike the electrically neutral photon of quantum electrodynamics ( QED ), gluons themselves carry color charge and therefore participate in the strong interaction in addition to mediating it, making QCD significantly harder to analyze than QED.

Quantum Effect Devices ( QED ), a separate company started by former MIPS employees, designed the R4600 Orion, the R4700 Orion, the R4650 and the R5000.

Because the muon is a lepton, the atomic energy levels of muonium can be calculated with great precision from quantum electrodynamics ( QED ), unlike the case of hydrogen, where the precision is limited by uncertainies related to the internal structure of the proton.

These lectures were transcribed and published as Feynman ( 1985 ), QED: The strange theory of light and matter, a classic non-mathematical exposition of QED from the point of view articulated below.

In quantum electrodynamics ( or QED ), the electromagnetic field has a ground state, the QED vacuum, which can mix with the excited stationary states of the atom ( for more information, see Ref.

The theory of the weak interaction can be called Quantum Flavordynamics ( QFD ), in analogy with the terms QCD and QED, but in practice the term is rarely used because the weak force is best understood in terms of electro-weak theory ( EWT ).

Richard Feynman, one of the originators and early developers of the theory of quantum electrodynamics ( QED ), referred to the fine-structure constant in these terms:

If the theory is renormalizable ( see below for more on this ), as it is in QED, the divergent parts of loop diagrams can all be decomposed into pieces with three or fewer legs, with an algebraic form that can be canceled out by the second term ( or by the similar counterterms that come from and ).

For example, in quantum electrodynamics ( QED ), an electron appears to be composed of electrons, positrons ( anti-electrons ) and photons, as one views it at higher resolution, at very short distances.

In the theory of quantum electrodynamics ( QED ), in which the electron-photon interaction is treated perturbatively, the calculation of the electron's magnetic moment has been found to agree with experiment to eleven decimal places.

However, in both Quantum Electrodynamics ( QED ) and Stochastic Electrodynamics ( SED ), consistency with the principle of Lorentz covariance and with the magnitude of the Planck Constant requires it to have a much larger value of 10 < sup > 113 </ sup > Joules per cubic meter.

It has been argued that due to the broken symmetry ( in QED ), free energy does not violate conservation of energy, since the laws of thermodynamics only apply to equilibrium systems.

The electroweak theory is obtained by combining SU ( 2 ) with U ( 1 ), where quantum electrodynamics ( QED ) is described by a U ( 1 ) group, and is replaced in the unified electroweak theory by a U ( 1 ) group representing a weak hypercharge rather than electric charge.

An example is quantum electrodynamics ( QED ), where one finds by using perturbation theory that the beta function is positive.

The QFT describing the interactions of photons and charged particles is quantum electrodynamics ( QED ), and this theory is not scale-invariant.

In physics, the Lamb shift, named after Willis Lamb ( 1913 – 2008 ), is a small difference in energy between two energy levels and ( in term symbol notation ) of the hydrogen atom in quantum electrodynamics ( QED ).

In 1943 he came up with a renormalization program to attack the problems of infinities in quantum electrodynamics ( QED ), but his paper was rejected by the Physical Review.

The background field is introduced as a Lorentz force in the ( classical ) Abraham-Lorentz-Dirac equation ( see: Abraham – Lorentz – Dirac force ), where the classical statistics of the electric and magnetic fields and quadratic combinations thereof are chosen to match the vacuum expectation values of the equivalent operators in QED.

If a lepton-antilepton pair is created, this process involves only quantum electrodynamics ( QED ), but if a quark-antiquark pair is created, it involves both QED and perturbative quantum chromodynamics ( QCD ).

He has published articles about SHC in New Scientist and Fortean Times, and has appeared on the BBC television programmes Newsnight and QED (" The Burning Question ").

He writes: " The radiation reaction and the vacuum fields are two aspects of the same thing when it comes to physical interpretations of various QED processes including the Lamb shift, van der Waals forces, and Casimir effects.
