Query: A simpel and versatile cold-atom simulator of non-Abelian gauge
  potentials   We show how a single, harmonically trapped atom in a tailored magnetic field
can be used for simulating the effects of a broad class of non-abelian gauge
potentials. We demonstrate how to implement Rashba or Linear-Dresselhaus
couplings, or observe {\em Zitterbewegung} of a Dirac particle.
