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…

Artificial atoms from cold bosons in one dimension
We investigate the ground-state properties of weakly repulsive onedimensional bosons in the presence of an attractive zero-range impurity potential. First, we derive mean-field solutions to the
Interacting bosons in a nearly resonant potential well
We establish that the ability of a localized trapping potential to bind weakly interacting bosons is dramatically enhanced in the vicinity of the threshold of formation of the single-particle bound
Trapping collapse: Infinite number of repulsive bosons trapped by a generic short-range potential
Weak potential wells (or traps) in one and two dimensions, and the potential wells slightly deeper than the critical ones in three dimensions, feature shallow bound states with localization length

Monotonicity of Quantum Ground State Energies: Bosonic Atoms and Stars
AbstractThe N-dependence of the non-relativistic bosonic ground state energy ℰB(N) is studied for quantum N-body systems with either Coulomb or Newton interactions. The Coulomb systems are “bosonic

Bose–Einstein condensation of atomic gases
Condensates have become an ultralow-temperature laboratory for atom optics, collisional physics and many-body physics, encompassing phonons, superfluidity, quantized vortices, Josephson junctions and quantum phase transitions.
Atoms with Bosonic "Electronis" in Strong Magnetic Fields
Abstract. We study the ground state properties of an atom with nuclear charge Z and N bosonic "electrons" in the presence of a homogeneous magnetic field B. We investigate the mean field limit $ N
Structure of a quantized vortex in boson systems
SummaryFor a system of weakly repelling bosons, a theory of the elementary line vortex excitations is developed. The vortex state is characterised by the presence of a finite fraction of the
Theory of Bose-Einstein condensation in trapped gases
The phenomenon of Bose-Einstein condensation of dilute gases in traps is reviewed from a theoretical perspective. Mean-field theory provides a framework to understand the main features of the
Asymptotics of heavy atoms in high magnetic fields: I. Lowest landau band regions
The ground state energy of an atom of nuclear charge Ze in a magnetic field B is evaluated exactly to leading order as Z ∞. In this and a companion work (see [28]) we show that there are five regions
Stable 85Rb bose-einstein condensates with widely tunable interactions
Bose-Einstein condensation has been achieved in a magnetically trapped sample of 85Rb atoms. Long-lived condensates of up to 10(4) atoms have been produced by using a magnetic-field-induced Feshbach
Low-dimensional bose liquids: beyond the gross-pitaevskii approximation
The Gross-Pitaevskii approximation is a long-wavelength theory widely used to describe a variety of properties of dilute Bose condensates, in particular trapped alkali gases. We point out that for
Realization of Bose-Einstein condensates in lower dimensions.
The crossover into two-dimensional and one-dimensional condensates was observed by a change in aspect ratio and by the release energy converging to a nonzero value when the number of trapped atoms was reduced.

It is shown that near the points where the dot charge is half-integer the thermodynamic characteristics show a non-analytic behavior identical to that of the two-channel spin-1/2 Kondo model.
