A True One-Dimensional Atomic System
A true one-dimensional atomic system, consisting of a Bose Einstein condensate (BEC) of rubidium atoms pulled out into a thin tubelike shape, has been experimentally demonstrated for the first time, in the ETH lab in Zurich. 1D ensembles of atoms should play an important role wherever precision handling of atoms is needed: in atom optics, atom interferometry, or sending signals from atom lasers down an atom waveguide.
