Photon echo with a few photons in two-level atoms
... Among the rich harvest of AFC results, most of them have been obtained in a simplified scheme where the storage medium operates as a pre-programmed delay line, rather than as an ondemand memory. The single photon level has been reached quite recently in on-demand memory conditions [13, 14], where st ...

Atoms – How Small, and How Large!

The concept of atoms was conceived in the great minds of thinkers like Kanaada in India, and Democritus in Greece, almost in the 5th century BC. Atoms moved from philosophy to science when chemis ...

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.
