There they were, in all their weird quantum glory: ultracold lithium atoms in the optical trap operated by UC Santa Barbara undergraduate student Alec Cao and his colleagues in David Weld’s atomic physics group. Held by lasers in a regular, lattice formation and “driven” by pulses of energy, these atoms were doing crazy things.
