ABSTRACT

We constructed a matter-wave beam splitter on an atom chip using a 87Rb Bose–Einstein condensate. Using radio-frequency-induced double-well potentials, we were able to coherently split a BEC into two clouds separated by distances ranging from 2.8 to 57 μm. Interference between these two freely expanding BECs was observed, confirming the coherence of the matter-wave beam splitter. We are able to control the distance and the angle between the split BECs by varying the rf-field’s amplitude, frequency, or polarization. From the perspective of practical use, our BEC manipulation system is suitable for application to interferometry. It is compact, and by anodic bonding the atom chip to the vacuum cell, the repetition rate is kept high. The portable system occupies a volume of 0.5 m3 and operates at a repetition rate as high as ~0.2 Hz using a commercial vacuum product. More... »
