Low-energy electron–argon scattering in a low-frequency laser field
... In the second case, the laser beam enters the scattering region in a direction such that its polarization direction ˆ bisects the angle between the incident direction and outgoing direction of the electron. The low-frequency KWA formula has a simple form. The cross section for absorbing n photons i ...

They are actually slightly discrete, because of the Polly's extrusion principle, which tells that no two electrons can actually have the same set of quantum numbers. Therefore, if you look closely there may be ...

Quantum Field Theory on Curved Backgrounds. I
... The Euclidean approach to quantum field theory on a curved background has advantages since elliptic operators are easier to deal with than hyperbolic operators. To obtain physically meaningful results one must presumably perform the analytic continuation back to real time. In general, Lorentzian spa ...

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.
