摘要:

我们已经制作并测试了一个原子芯片,它可以作为一个物质波干涉仪。在这篇文章中,我们描述了通过离子束铣削蒸发到硅衬底上的金来制造芯片。我们目前的数据上的质量的电线,在电流密度,可以达到的电线和形成的磁陷阱的平滑度。我们演示了干涉仪的操作,表明我们可以相干分裂和重组的玻色-爱因斯坦凝聚体具有良好的相稳定性。

英文摘要:

We have fabricated and tested an atom chip that operates as a matter wave interferometer. In this communication we describe the fabrication of the chip by ion-beam milling of gold evaporated onto a silicon substrate. We present data on the quality of the wires, on the current density that can be reached in the wires and on the smoothness of the magnetic traps that are formed. We demonstrate the operation of the interferometer, showing that we can coherently split and recombine a Bose-Einstein condensate with good phase stability.
