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.

Atom interferometry with ultra-cold atoms
Summaries of Papers Presented at the Quantum Electronics and Laser Science Conference, 2003Summary form only given. Recent advances in the field of atom interferometry have opened the possibility of a new class of precise and accurate inertial force sensors. We have built laboratory prototypes of accelerometers, gravity gradiometers and gyroscopes based on atom interference principles which now perform at levels which compare favorably with ...

Photoassociation of Cold Ca Atoms
Physical Review Letters, 2000We present the first measurement of a photoassociative spectrum of an alkaline earth element near the dissociation limit. The observed spectrum of Ca2 formed from cold atoms shows the regular vibrational series with the characteristic spacing of the 1/R3 asymptotic potential.

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.

Cold collisions in an atomic beam
Physical Review A, 1990We report a measurement of the rate constant for associative ionization (AI) between excited Na(3{ital p}) atoms colliding within a single beam at a velocity of 11.9 msec{sup {minus}1}, corresponding to a temperature of 65 mK. The collisions take place in a narrow velocity class of excited atoms produced by crossing the collimated Na beam with a ...

Method for velocimetry of cold atoms
Physical Review A, 1994We describe our use of recoil-induced resonances or stimulated optical Compton scattering to measure the velocity distribution of laser-cooled cesium atoms in one dimension. The technique works well at velocities near 1 cm/s, is insensitive to the effects of light shifts or stray fields, requires only a few ${\mathrm{mm}}^{3}$ of work space, and may be

Abstract In the previous two chapters we have investigated how resonant light beams interact with atomic transitions, and the way this process can be modified by means of cavities. We now wish to explore a different aspect of the light–matter interaction, namely light-induced forces.

Since Bose-Einstein condensates were first realized in 1995, experimentalists have focused on characterizing and manipulating these weakly interacting systems. In their Perspective, Cirac and Zoller look ahead toward the next challenge for atomic physics: strongly interacting atomic systems that may be of use in quantum computing and may ...
