BEC1: An atomtronic matterwave interferometer
BEC 1 is concerned with trapped matterwave interferometry either in the fully trapped regime or in matterwave guides. We have recently demonstrated the first guiding of matterwaves over macroscopic distances without affecting the internal coherence of the Bose-Einstein Condensates (BEC), i.e. to guide them without any heating or atom-loss. The waveguides are formed from a combination of magnetic fields at different frequencies (ranging from DC, over LF and RF to microwaves).
We have recently managed to demonstrate the first fully coherent waveguides (published in Nature).
One possible version of the interferometer (trapped clock interferometer) is described here.
