Web22. aug 2015 · We present a new scheme for high-efficiency three-dimensional (3D) atom localization in a three-level atomic system via spontaneous emission. Owing to the space-dependent atom–field interaction, the position probability distribution of the atom can be directly determined by measuring the spontaneous emission. It is found that, by properly … Web16. jún 2024 · The key component of an atom laser is BEC, the fifth state of matter. BEC forms when a very diffuse gas is cooled, usually with lasers and evaporative cooling, to …
