A lattice of magneto-optical and magnetic traps for cold atoms

Basic periodic trapping configurations is presented, which can be realized with multilayer microstructures. The trapping fields for the atoms (Ioffe Pritchard type potentials for magnetic trapping of atoms as well as quadrupole fields for magneto-optical trapping) are formed by two layers of crossed wires, which can be individually addressed. The possibility of producing multiple magneto optical traps (MOT) next to a surface in a controlled manner will be shown. This could be a first step to load ultracold atoms into an array of microstructured magnetic traps in a parallel way.
