Nonlinear electron acceleration by oblique whistler waves - HAL-Insu
... observations have revealed the presence of whistler waves with extremely high amplitudes.24–26 These waves form short intense wave-packets with 10–104 wave-periods inside each packet.27 Spatial scales along the background magnetic field allow one single packet to be present over most of a field line ...

... is as follows: Let x denote the term being computed, and let β : x 7→ β(x) denote a single beta reduction step. Instead of the non-invertible function β, one considers the function x 7→ (x, β(x)), which is invertible on its range. In its simplest version, the computation proceeds as x 7→ (x, β(x)) 7 ...

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.
