Ifan G Hughes and Matthew J Pritchard
Show affiliationsThere has been dramatic progress recently in atomic physics. It is now routine at hundreds of laboratories worldwide to cool samples of atoms to microkelvin temperatures through a process called laser cooling. Bizarre as it may sound, it is possible to use lasers (which are usually associated with cutting and heating) to slow atoms from the jumbo-jet speed of a room temperature gas to a snail's pace. At these low temperatures exciting new physics is observed, and atoms are treated as waves. An overview of the physics principles that underlie this technique is given, as well as a few examples of recent progress in the emergent fields of atom optics and manipulation of coherent matter waves.
