Atomic transport in integrated magnetic microtraps

Summary form only given. Magnetic microtraps with current-carrying wires have initially been proposed in order to reach field configurations with high gradients. In our first demonstration of an electromagnetic microtrap, we used a lithography created wire on a substrate at room temperature to realize a quadrupole trap. Transverse gradients of 1600 G/cm were achieved with only 2A of current flowing, through the wire. More recently, we have extended this technique in Ioffe traps, which are more suitable for achieving long lifetimes at low temperatures. A moving chain of Ioffe-Pritchard traps can be created with a simple planar wire configuration. We present experimental results with this atom motor.
