Odd quantum property may let us chill things closer to absolute zero

A new type of cooling relies on an exotic quantum mechanical property instead of putting objects in a cold environment like a refrigerator — and it could one day help us cool things down to temperatures below what we’ve previously reached. Is.

How cold or hot something is depends on how the atoms in its constituents are vibrating, with hotter and higher temperatures moving faster and faster. Thus, cooling objects involves finding ways to slow down this atomic jiggle -…
