Destruction of interference by many-body interactions in cold atomic Bose gases
Destruction of interference by many-body interactions in cold atomic Bose gases
We study the effects of many-body interactions on the interference in a Mach-Zehnder interferometer for matter waves of ultracold Bose atoms. After switching off an axial trapping potential, the thermal initial wavepacket expands, and subsequently interference fringes may be observed in a circular 1D trap. These are computed for axial …
