Coherence Properties of Guided-Atom Interferometers
H. Kreutzmann, U. V. Poulsen, M. Lewenstein +4
We present a detailed investigation of the coherence properties of beam splitters and Mach-Zehnder interferometers for guided atoms. It is demonstrated that such a setup permits co…

Characterization and control of phase fluctuations in elongated Bose-Einstein condensates
H. Kreutzmann, A. Sanpera, L. Santos +7
Quasi one dimensional Bose-Einstein condensates (BECs) in elongated traps exhibit significant phase fluctuations even at very low temperatures. We present recent experimental resul…
