Dynamics of Bloch Oscillations in Disordered Lattice Potentials
T. Schulte, S. Drenkelforth, G. Kleine Büning +4
We present a detailed analysis of the dynamics of Bloch oscillations of Bose-Einstein condensates in disordered lattice potentials. Due to the disorder and the interparticle intera…
Collective excitation of Bose-Einstein condensates in the transition region between 3D and 1D
M. Kottke, T. Schulte, L. Cacciapuoti +4
We measure the frequency of the low m=0 quadrupolar excitation mode of weakly interacting Bose-Einstein condensates in the transition region from the 3D to the 1D mean-field regime…
Routes towards Anderson-Like localization of Bose-Einstein condensates in disordered optical lattices
T. Schulte, S. Drenkelforth, J. Kruse +5
We investigate, both experimentally and theoretically, possible routes towards Anderson-like localization of Bose-Einstein condensates in disordered potentials. The dependence of t…
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…
