Spectroscopic measurements of dense plasmas at billions of atmospheres provide tests to our fundamental understanding of how matter behaves at extreme conditions. Developing reliable atomic physics ...

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 ...

Atomic, molecular and optical (AMO) physics explores the quantum behaviour of electrons, atoms and light, and their mutual interactions across energy, length and time scales. In atoms and molecules, ...
