Researchers from Hanns-Christoph Nägerl's group have produced the world's first ultracold KCs molecules in their absolute ground state. Starting by mixing clouds of potassium and cesium atoms cooled ...

The air around us is a chaotic superhighway of molecules whizzing through space and constantly colliding with each other at speeds of hundreds of miles per hour. Such erratic molecular behavior is ...

Molecules containing four atoms are the largest yet to be cooled down to only a hundred billionths of a degree above absolute zero. The techniques researchers use for cooling individual atoms, such as ...
