The Aufbau principle determines an atom`s electron
... The Aufbau principle is based on the idea that the order of orbital energies is fixed—both for a given element and between different elements. This assumption is approximately true— enough for the principle to be useful—but not physically reasonable. It models atomic orbitals as "boxes" of fixed en ...

If electrons are not ejected from atoms but merely raised to higher energy levels (outer shells), the process is termed excitation, and the atom is said to be “excited.” Charged particles such as electrons, protons, and atomic nuclei are directly ionizing radiations because they can eject electrons ...

Generating entangled spin states for quantum metrology by single-photon detection
... q 1 is the photon detection efficiency. The probability of the incident photon being scattered into free space by the atomic ensemble is psc = 2Sη(/2)2 = 2Sφ 2 /η [35]. Therefore the success probability is simply related to the free-space scattering probability via p = qηpsc /4. A cavity increas ...

The discrepancies between predicted and measured wavelengths for line spectra other than hydrogen were enough to indicate that modifications would have to be made to Bohr’s theory of the atom. Another difficult ...

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.
