Molecules get a big chill
New method takes big atom groups closer to long-sought temperatures

Stopping big molecules cold in their tracks just got a little easier, thanks to a new trick that nudges them closer to ultracold temperatures.
Physicists have previously chilled atoms and pairs of atoms to fractions of a degree above absolute zero — a lab feat that has revealed new physics and chemistry of matter. Now, German scientists have started to do the same for molecules made of many atoms.
The work is “a real important step forward towards realizing cold and ultracold molecular sa...
