Ground-state properties of artificial bosonic atoms, Bose interaction blockade, and the single-atom pipette
@article{Kolomeisky2004GroundstatePO, title={Ground-state properties of artificial bosonic atoms, Bose interaction blockade, and the single-atom pipette}, author={Eugene B. Kolomeisky and Joseph P Straley and Ryan M. Kalas}, journal={Physical Review A}, year={2004}, volume={69}, pages={063401} }
We analyze the ground-state properties of an artificial atom made out of repulsive bosons attracted to a center for the case that all the interactions are short ranged. Such bosonic atoms could be created by optically trapping ultracold particles of alkali-metal vapors; we present the theory describing how their properties depend on experimentally adjustable strength of 'nuclear' attraction and interparticle repulsion. The binding ability of the short-range potential increases with space…

A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled and exhibited a nonthermal, anisotropic velocity distribution expected of the minimum-energy quantum state of the magnetic trap in contrast to the isotropic, thermal velocity distribution observed in the broad uncondensed fraction.
