By first cooling atoms to ultralow temperatures and only then forming molecules, the group succeeded in creating an ultracold gas of molecules, measuring one thousand times colder than what can be achieved by direct cooling techniques.
He shared the 1997 Nobel Prize in physics for his work trapping and cooling atoms using laser light.
What we are doing here is cooling atoms down from the normal temperature in gas to something which is so cold that they all march in step a bit like light in a laser beam.
