Here is a bit more on what is happening:

This arrangement is known as a magneto-optical trap and using it the atoms can be made colder than anywhere else in the universe, cold enough for the subtle effects of quantum mechanics to make the wavefunction of the atoms coherent, just like how a laser makes the photons in a laser medium coherent. The wavefunctions then constructively interfere until the atoms behave as a single quantum object known as a Bose-Einstein Condensate.

In quantum mechanics, a class of particles which have an integer quantum spin are called bosons. For example, photons, gluons, higgs boson etc. Any number of bosons can go to the same quantum state. Thus they obey Bose-Einstein statistics. The wave function associated with bosons is symmetric.

We hope you enjoy the video who knew this was possible?
