TL;DR: In this article, Bose-Einstein condensation of sodium atoms was observed in a novel trap that employed both magnetic and optical forces, which increased the phase-space density by 6 orders of magnitude within seven seconds.

Bose-Einstein condensation in a gas of sodium atoms
TL;DR: The striking signature of Bose condensation was the sudden appearance of a bimodal velocity distribution below the critical temperature of ~2µK.
Journal ArticleDOI
High densities of cold atoms in a dark spontaneous-force optical trap.
TL;DR: A new magneto-optical trap is demonstrated which confines atoms predominantly in a «dark» hyperfine level, that does not interact with the trapping light, that leads to much higher atomic densities as repulsive forces between atoms due to rescattered radiation are reduced and trap loss due to excited-state collisions is diminished.
Journal ArticleDOI
Evaporative cooling of sodium atoms.
TL;DR: Rf induced evaporation was used to reduce the temperature by a factor of 12 and increase the phase space density by more than 2 orders of magnitude and the elastic collision cross section of cold sodium atoms in the minus-1 hyperfine state was determined to be 6 times 10 cm2, which implies a positive value of the scattering length.
Journal ArticleDOI
An analytical model for evaporative cooling of atoms
TL;DR: In this article, a truncation of the high-energy tail of the thermal distribution followed by collisional relaxation is proposed for the evaporation of trapped atoms, which is solved analytically for arbitrary power-law potentials.
