... In the second section, we provide an analytic diagonalization of the Dirac operator. Our approach leads to a complete split of the particle and antiparticle parts into two non-hermitian components, which are mapped into each other by the charge conjugation transformation. Thus, the full matrix-value ...

... The photon energy E is given by E=hf where h is Planck’s constant and f is the frequency of the incident radiation. If f equals the threshold frequency, photoelectrons will only just escape the surface and they have zero kinetic energy, so the photon energy = the work function energy. The Work funct ...

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.
