Towards an effective field theory on the light-shell
... Previously, [1] we expressed the hope of constructing an effective field theory on the 2-dimensional light-shell emerging from a high-energy collision. The idea was motivated by a classical picture of a very high energy hadronic collision in which colored particles are produced from an initially col ...

Let us note that the spectral width along þ is determined by the pump bandwidth which for a quasi-monochromatic pump (e.g. in the MHz range) is typically orders of magnitude smaller than the width of the PMF along þ . The cooperativity parameter (also known as the Schmidt number) K is a convenient ...

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.
