ATOMIC CLOCKS AND COLD ATOM SCATTERING
Laser Spectroscopy, 2002We demonstrate a Rb fountain clock which has a small cold collision shift that is cancelled by detuning the microwave cavity. To further enhance the stability and accuracy, we are currently developing a new state detection technique that directly measures population differences and are juggling atoms in the fountain. Fountain clocks also enable a novel

AIP Conference Proceedings, 2001
This paper reviews recent progress on microwave clocks using laser cooled neutral atoms. With an ultra-stable cryogenic sapphire oscillator as interrogation oscillator, a cesium fountain operates at the quantum projection noise limit. With 6 105 detected atoms, the relative frequency stability δν/ν is 4 10−14τ−1/2 where τ is the integration time in ...

Physica Scripta, 2004
Cold antihydrogen atoms have been produced in two experiments at CERN's Antiproton Decelerator (AD). Future spectroscopy of antihydrogen has the potential for extremely precise tests of the fundamental symmetry between matter and antimatter. Recent experiments and future developments will be discussed.

Abstract Laser cooling is an elegant and important tool that has been useful in many branches of atomic physics. For example, laser cooling has enabled the creation and study of Bose-Einstein condensates of dilute atomic vapors (Anderson et al. 1995, Bradley et al. 1995, Davis et al.
