A cloud of ultracold atoms is like a motel with a neon “no vacancy” sign. If a guest at the motel wants to switch rooms, they’re out of luck. No vacant rooms means there’s no choice but to stay put.

Cold atom physics has emerged as a cornerstone of modern quantum science, enabling precise manipulation of atomic ensembles through techniques such as laser cooling and magneto-optical trapping. At ...

Atom interferometry has emerged as a transformative approach in both fundamental physics and practical applications, utilising the wave nature of atoms to measure minute effects of gravity, rotation ...
