A grand challenge of ultracold physics is figuring out how fermions become bosons. This is an important question because the tiniest quantum particles of matter are all fermions. However, these fermions can form larger chunks of matter, such as atoms and molecules, which can be either fermions or bosons.

An interesting feature of fermions and bosons is that they behave very differently...

What happens to a Bose-Einstein condensate (BEC) when its atoms interact strongly? One possibility for large attractive interactions is that the condensate shrinks and then explodes, as the Cornell and Wieman groups discovered in 2001. Another possibility for large repulsive interactions is behavior analogous to that of superfluid liquid helium. If superfluid liquid heliumlike dynamics could...
