Ground-State Properties of Magnetically Trapped Bose-Condensed Rubidium Gas

Abstract

We give a quantitative account of the ground-state properties of the dilute magnetically trapped 87Rb gas recently cooled and Bose-Einstein condensed at nanokelvin-scale temperatures. Using simple scaling arguments, we show that at large particle number the kinetic energy is a small perturbation, and find a spatial structure of the cloud of atoms and its momentum distribution dependent in an essential way on particle interactions. We also estimate the superfluid coherence length and the critical angular velocity at which vortex lines become energetically favorable.
