Degenerate quantum gases manipulation on AtomChips

The integration of cold atomic sources and electromagnetic field sources in the same device is a major frontier for both fundamental science and advanced technology. In this paper, we discuss the realization of the Bose–Einstein condensate (BEC) on an AtomChip and describe such an experimental configuration realized at LENS. We also concentrate on the realization of a particular integrated matter wave interferometer where coherent coupling between the BECs in different Zeeman states is used to produce a fringe time-population signal at the output. Finally, we discuss the prospects for application of such a device as a multi-path interferometer.
