Atomtronics: A new phase

Just as NASA engineers test new rocket designs in computer studies before committing themselves to full prototypes, so physicists will often model matter under various circumstances to see whether something new appears. This is especially true of atomtronics, a relatively new science devoted to creating artificial tailored materials consisting of neutral atoms held in an array with laser beams, or atoms moving along a desired track under electric or magnetic influence. A new study* shows how a simple "joystick" consisting of an adjustable magnetic field can create several new phases of atomtronic matter, several of them never seen before. Charles Clark, Co-Director of the Joint Quantum Institute will report the results at the meeting of the American Association for the Advancement of Science (AAAS) in Vancouver.
