This paper describes the process for creating and validating an assessment test that measures the effectiveness of instruction by probing how well that instruction causes studen...
We have measured the elastic-scattering cross section of $^{87}\mathrm{Rb}$ atoms in the \ensuremath{\Vert}F=1,${\mathit{m}}_{\mathit{F}}$=-1〉 ground state at 25 \ensuremath{\mu...
A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled. The condensate fraction first appeared nea...
We have produced a very cold sample of spin-polarized trapped atoms. The technique used dramatically simplifies the production of laser-cooled atoms. In this experiment, 1.8\ifm...
We describe experiments that show collective behavior in clouds of optically trapped neutral atoms. This collective behavior is demonstrated in a variety of observed spatial dis...
We have measured the elastic collision cross section for spin polarized atomic cesium. Neutral cesium atoms are optically cooled, then loaded into a dc magnetic trap. We infer t...
A classical collective behavior is observed in the spatial distributions of a cloud of optically trapped neutral atoms. They include extended uniform-density ellipsoids, rings o...
