Physicists Just Cooled Molecules to a Hair Above Absolute Zero

Many scientists say that reaching absolute zero is a lot like traveling at the speed of light: impossible. Well, some MIT scientists almost pulled a Doc Brown and got a lot closer to the impossible goal by cooling a molecule to 500 nanokelvins. That’s just above absolute zero and about a million times colder than… » 6/16/15 1:20pm 6/16/15 1:20pm

Physicists Use Lasers to Chill the World's Coldest Molecules

If you thought last winter was cold, you should stay as far away from magneto-optical trapping as possible. Yale physicists recently used this technique to cool a molecule of strontium monoflouride down to 2.5 thousandths of a degree above absolute zero. That makes them the world's coldest molecules. » 8/25/14 10:54am 8/25/14 10:54am
