Abstract
The ground-state properties of artificial bosonic atoms created by optically trapping ultracold particles of alkali-metal vapors were investigated. The impact of the strength of nuclear attraction and interparticle repulsion on the bosonic atoms as well as Bose interaction blockade and single-atom pipette was also discussed. The increase in space dimensionality increased the ability of the short-range potential and in one dimension only a limited number of particles were bound. The dependence of the ground-state energy of the atom on the number of particles was found to be minimum because of the competing nuclear attraction enhanced by the Bose statistics and interparticle repulsions.
