Ultra-cold atoms and Bose-Einstein condensates (BECs) provide a dramatic example of a quantum system on a macroscopic scale. Atoms can be cooled down to temperatures below 1μK and their de Broglie wavelengths become large enough to be readily observed in experiments. This has spawned a new research area known as atom optics which refers to the study and control of atoms based on their wave nature. In recent years, physicists have been performing experiments with coherent atoms from a Bose-Einstein condensate. The ability to produce and manipulate condensates above microfabricated surfaces may one day lead to new technologies such as atom interferometers on a chip.Ultra-cold atoms and Bose-Einstein condensates (BECs) provide a dramatic example of a quantum system on a macroscopic scale.

Designing Bose--Einstein Condensate Interferometers

Mark Edwards, Charles W. Clark

Summary form only given. In a recent experiment, performed at the National Institute of Standards and Technology (NIST), a Mach-Zender type matter-wave interferometer was demonstrated using a sequence of laser pulses applied to a gaseous Bose-Einstein condensate. Matter-wave interferometers are essential tools for probing optically manipulated Bose-Einstein condensates (BECs) and the use of a sequence of laser pulses should enable experimenters to implement a variety of interferometer types tailored for particular applications.Summary form only given.

Dipolar decay in two recent Bose-Einstein condensation experiments

H. M. J. M. Boesten, A. J. Moerdijk, BOUDEWIJN J. VERHAAR

In view of two recent Bose-Einstein condensation experiments, we have calculated the magnetic-dipolar decay-rate constants of the atomic density for the doubly polarized state in $^{87}\mathrm{Rb}$ and $^{85}\mathrm{Rb}$ , and for the highest state of the lower hyperfine manifold in $^{23}\mathrm{Na}$ .In view of two recent Bose-Einstein condensation experiments, we have calculated the magnetic-dipolar decay-rate constants of the atomic density for the doubly polarized state in $^{87}\mathrm{Rb}$ and $^{85}\mathrm{Rb}$, and for the highest state of the lower hyperfine manifold in $^{23}\mathrm{Na}$.
