Micromotion of a Bose-Einstein-condensate in a dynamic trap

Summary form only given. In a time-orbiting-potential-trap (TOP-trap), atoms are confined by a combination of a static quadrupole field and a rotating bias field. Despite its widespread use, the effects of the micromotion of the atoms in such a trap have not been extensively studied so far. In this work, we experimentally investigate the micromotion of a Rb Bose-Einstein condensate in a triaxial TOP-trap and compare our findings with a theoretical model and numerical simulations.
