What happened

Miniaturized laser technology paves the way for fundamental physics experiments in space Sadie Harley Scientific Editor Robert Egan Senior Editor An international team of researchers has succeeded in producing atomic quantum gas mixtures with an unprecedented…

Why it matters

In the journal Nature Communications, the scientists report on experiments conducted with the MAIUS-B apparatus, in which Bose–Einstein condensates (BECs) consisting of two different atomic species—rubidium and potassium—were generated and studied under…

Common ground

A key contribution to this achievement came from a technological development at Johannes Gutenberg University Mainz (JGU): the highly sophisticated and compact optical system used to control the atoms.
