Journal ArticleDOI
Matter-wave interferometry in a double well on an atom chip
Thorsten Schumm,Thorsten Schumm,Sebastian Hofferberth,L. M. Andersson,S. Wildermuth,S. Groth,S. Groth,Israel Bar-Joseph,Jörg Schmiedmayer,Peter Krüger +9 more
TL;DR: In this paper, an integrated interferometer based on a simple coherent matter-wave beam splitter constructed on an atom chip is presented, where the authors demonstrate the splitting of Bose-Einstein condensates into two clouds separated by distances ranging from 3 to 80μm.
Journal ArticleDOI
Adiabatic radio-frequency potentials for the coherent manipulation of matter waves
Igor Lesanovsky,Thorsten Schumm,Thorsten Schumm,Sebastian Hofferberth,L. M. Andersson,L. M. Andersson,Peter Krüger,Jörg Schmiedmayer +7 more
TL;DR: Adiabatic dressed state potentials as discussed by the authors are created when magnetic substates of trapped atoms are coupled by a radio-frequency field, and they can be realized using simple and highly integrated wire geometries on atom chips.
Journal ArticleDOI
Potential roughness near lithographically fabricated atom chips
Peter Krüger,Peter Krüger,L. M. Andersson,S. Wildermuth,Sebastian Hofferberth,Sebastian Hofferberth,Elmar Haller,Simon Aigner,S. Groth,S. Groth,Israel Bar-Joseph,Jörg Schmiedmayer +11 more
TL;DR: A detailed analysis of the magnetic field roughness of a 100-mu m-wide wire shows that these potentials stem from minute variations of the current flow caused by local properties of the wire rather than merely from rough edges as mentioned in this paper.
Journal ArticleDOI
A Double Well Interferometer on an Atom Chip
Thorsten Schumm,Peter Krüger,Sebastian Hofferberth,Igor Lesanovsky,S. Wildermuth,S. Groth,Israel Bar-Joseph,L. M. Andersson,Jörg Schmiedmayer +8 more
TL;DR: Radio-Frequency coupling between magnetically trapped atomic states allows to create versatile adiabatic dressed state potentials for neutral atom manipulation, and this work uses this to build an integrated matter wave interferometer on an atom chip.
Journal ArticleDOI
Microtraps and Atom Chips: Toolboxes for Cold Atom Physics
TL;DR: Magnetic microtraps and Atom Chips are safe, small-scale, reliable and flexible tools to prepare ultra-cold and degenerate atom clouds as sources for various atom-optical experiments as mentioned in this paper.
