Bose-Einstein Condensates in Combined Optical and Magnetic Potentials

Bose-Einstein Condensates (BECs) of ultracold alkali atoms are typically studied in harmonic magnetic traps or highly regular, periodic optical lattices. More complex trapping potentials can be formed by combinations of magnetic and optical fields. I will describe experiments performed at the University of Queensland on BEC formation and coherence in highly elongated magnetic traps and in the combination of a far off-resonant optical dipole trap (FORT) with a magnetic trap. I will also present preliminary results on condensate dynamics in the highly anharmonic combined trap.
