A new type of cooling relies on an exotic quantum mechanical property rather than putting objects into cold environments like refrigerators – and it might one day help us chill things to temperatures lower than any we have reached before.

How cold or warm an object is depends on how its constituent atoms are jiggling, with more and faster jiggling corresponding to more heat and a higher temperature. As such, making objects colder involves finding ways to slow that atomic jiggling –…
