Adiabatic radio frequency potentials for the coherent manipulation of matter waves
I. Lesanovsky, T. Schumm, S. Hofferberth +3
Adiabatic dressed state potentials are created when magnetic sub-states of trapped atoms are coupled by a radio frequency field. We discuss their theoretical foundations and point…
A simple quantum gate with atom chips
M. A. Cirone, A. Negretti, T. Calarco +2
We present a simple scheme for implementing an atomic phase gate using two degrees of freedom for each atom and discuss its realization with cold rubidium atoms on atom chips. We i…
Disorder Potentials near Lithographically Fabricated Atom Chips
P. Kruger, L. M. Andersson, S. Wildermuth +6
We show that previously observed large disorder potentials in magnetic microtraps for neutral atoms are reduced by about two orders of magnitude when using atom chips with lithogra…
Atom Chips: Fabrication and Thermal Properties
S. Groth, P. Krüger, S. Wildermuth +5
Neutral atoms can be trapped and manipulated with surface mounted microscopic current carrying and charged structures. We present a lithographic fabrication process for such atom c…
Optimized U-MOT for experiments with ultracold atoms near surfaces
S. Wildermuth, P. Krüger, C. Becker +5
We present an integrated wire-based magnetooptical trap for the simplified trapping and cooling of large numbers of neutral atoms near material surfaces. With a modified U-shaped c…
Trapping and manipulating neutral atoms with electrostatic fields
P. Krüger, X. Luo, M. W. Klein +7
We report on experiments with cold thermal Li atoms confined in combined magnetic and electric potentials. A novel type of three-dimensional trap was formed by modulating a mag…
