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.

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 ...

Cold antihydrogen atoms have been produced recently by mixing trapped antiprotons with cold positrons. The efficiency is remarkable: more than 10% of the antiprotons form antihydrogen. Future spectroscopy of antihydrogen has the potential to provide new extremely precise tests of the fundamental symmetry between matter and antimatter. In addition, cold

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.

Detection of weak magnetic fields with high spatial resolution is an important technology for various applications such as biological imaging, detection of MRI signals and fundamental physics. Cold atom magnetometry enables 10−11 T/\(\sqrt{\text{Hz}}\) sensitivities at the micron scale, that is, at the scale of a typical biological cell size.
