The results are an important stress test for theories and future experiments in atomic physics. 1.97007 femtometre (quadrillionths of a metre): That’s how unimaginably tiny the radius of the atomic ...

For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and ...

Photoionization, the process by which an incident photon ejects an electron from an atom, lies at the heart of many atomic physics studies. Coupled with cross section measurements – which quantify the ...

The 53rd Annual Meeting of the American Physical Society’s Division of Atomic, Molecular and Optical Physics begins May 30. Scientists from around the world will present new findings on atoms, simple ...

Delve into the detail of atomic physics. As the basic units of matter, atoms are the building blocks for everything in the universe. Once thought to be indivisible, we now know they can indeed be ...

Gaby and Alex’s team developed a chip-scale atomic clock (CSAC) that is a little larger than a peanut. Rubidium atoms in the atomic beam provide the microwave quantum transition that is used by the ...
