Trap** and manipulating ultracold atoms and degenerate quantum gases in magnetic
micropotentials is reviewed. Starting with a comprehensive description of the basic concepts …

Elongated atom traps can confine ultracold gases in the quasi-one-dimensional regime. We
review both the theory of these atom waveguides and their experimental realizations, with …

A trapped-atom interferometer was demonstrated using gaseous Bose-Einstein
condensates coherently split by deforming an optical single-well potential into a double-well …

Abstract Although Bose–Einstein condensates,, of ultracold atoms have been experimentally
realizable for several years, their formation and manipulation still impose considerable …

Scientific and technological progress in the last decades has proven that miniaturization and
integration are important steps towards the robust application of fundamental physics, be it …

We report the coherent manipulation of internal states of neutral atoms in a magnetic
microchip trap. Coherence lifetimes exceeding 1 s are observed with atoms at distances of 5 …

Potentials for atoms can be created by external fields acting on properties such as magnetic
moment, charge, polarizability, or by oscillating fields that couple internal states. The most …

Adiabatic dressed state potentials are created when magnetic substates of trapped atoms
are coupled by a radio-frequency field. We discuss their theoretical foundations and point …

We describe an experiment in which Bose-Einstein condensates and cold atom clouds are
held by a microscopic magnetic trap near a room-temperature metal wire 500 μ m in …

We have measured magnetic trap lifetimes of ultra-cold 87 Rb atoms at distances of 5–1000
µm from surfaces of conducting metals with varying resistivity. Good agreement is found with …
