What do you get when you superimpose a rotating pattern of intersecting laser beams on a spinning cloud of ultracold atoms in a thin gas? Pretty pictures, for one thing--but also a new method that ...
This set of JILA images shows a rotating Bose-Einstein condensate (BEC) "pinned" to a rotating lattice created with lasers as the shape of the combined "vortex lattice" evolves from triangular (top) ...
