Transporting, splitting and merging of atomic ensembles in a chip trap
P. Hommelhoff, W. Hänsel, T. Steinmetz, T. W. Hänsch, J. Reichel
abstract: We present a toolbox for cold atom manipulation with time-dependent magnetic
fields generated by an atom chip. Wire layouts, detailed experimental
procedures and results are presented for the following experiments: Use of a
magnetic conveyor belt for positioning of cold atoms and Bose-Einstein
condensates with a resolution of two nanometers; splitting of thermal clouds
and BECs in adjustable magnetic double well potentials; controlled splitting of
a cold reservoir. The devices that enable these manipulations can be combined
with each other. We demonstrate this by combining reservoir splitter and
conveyor belt to obtain a cold atom dispenser. We discuss the importance of
these devices for quantum information processing, atom interferometry and
Josephson junction physics on the chip. For all devices, absorption-image video
sequences are provided to demonstrate their time-dependent behaviour.
