... Effective nuclear charge is the apparent nuclear charge exerted on a particular electron, equal to the actual nuclear charge minus the effect of electron repulsions. We often focus on the effective nuclear charge felt by the outermost electron which is shielded significantly by core electrons and so ...

... meaningless (see Bella 1999) – that is, reality is a construct. What we experience as true or not true, as present versus the past, as an object here rather than somewhere else, is all questioned because of the strange findings of quantum physics. I would like, now, to turn our attention to another ...

... If two particles interact with each other (like an electron and a proton in a hydrogen atom) then there are not two wavefunctions (one for the electron and one for the proton) there is just one wavefunction, Ψ(xe,ye,ze,xp,yp,zp,t). This wavefunction describes the joint probability of finding an ele ...

Expanding on our work on indefinite spectral triples (arXiv:1611.07062) applied to the standard model on Lorentzian space-times, we show that many axioms of spectral triples can be recovered from a GUT based on the gauge group SO(4,6). The connection between this GUT and NCG resides in the use of Cl ...

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.
