This action which splits the beam must have the effect of “spreading out the electrons” in a manner that the average spacing, x, is now doubled (if we assume the beam splitter is a 50/50 beam splitter with two outputs of roughly half the intensity of the input beam). This action of spreading out the ...

... the Standard Model has, plus also the development of Effective Field Theory (EFT). So, although while many people made important progress as each new tool came into existence, we really did not have all the tools in place until the 1990s. So, let us imagine starting over. We can set out to develop a ...

By expanding this singlet the coefficients for both spin up and spin down, particles A and B, result in a ½ chance. Bec ...

... The ratio of charge to mass of the electron was first determined by J.J. Thomson in 1897. For many years afterwards, only the ratio was known; the charge and the mass being so small they eluded measurement. This remained the case until Millikan measured e by using charged oil drops (1911). In Thomso ...

One can argue as follows: for a particle of given charge, the amount of energy lost by bremsstrahlung depends on its acceleration; the acceleration is provided by the electric field due to the nuclei of the medium through which the particle is ...

Quantum electrodynamics



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. 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.In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum. Richard Feynman called it ""the jewel of physics"" for its extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen.
