In 1924 the Indian physicist Satyendra Nath Bose sent Einstein a paper in which he derived the Planck law for black-body radiation by treating the photons as a gas of identical particles. Einstein…

It is demonstrated that Bose condensed atoms are “laser-like”; that is, they are coherent and show long-range correlations and have direct implications for the atom laser and the Josephson effect for atoms.

We have demonstrated an output coupler for Bose condensed atoms in a magnetic trap. Short pulses of rf radiation were used to create Bose condensates in a superposition of trapped and untrapped…
Propagation of Sound in a Bose-Einstein Condensate

Sound propagation has been studied in a magnetically trapped dilute Bose-Einstein condensate. Localized excitations were induced by suddenly modifying the trapping potential using the optical dipole…

A cloud of ultracold atoms confined in a magneto-optical trap (MOT) has a temperature greater than that of a low-density vapour in the same light field. It has been observed (Drewsen M. et al., Appl.…

[S0031-9007(98)05702-0] We predicted that density perturbations should propagate along the axis of a cigar-shaped Bose-Einstein cond at a speedc sn0Ũymd, wheren0 is the density at the center of the…
Bose-Einstein-condensation and prospects for precision measurements

Summary form only given. In the past year, within a few months, three groups have independently succeeded in demonstrating Bose-Einstein condensation (BEC) in a gas of alkali atoms. Our initial…
An output coupler for Bose condensed atoms

The observations of BEC have stimulated interest in atom lasers, coherent sources of atomic matter waves. The build-up of atoms in the ground state of a magnetic trap is analogous to stimulated…
