Thermodynamic properties of a rotating Bose gas in harmonic trap
TL;DR: In this article, a simple semiclassical approximation, which is the density of state approach, is suggested to include the effects, such as the finite size and the chemical potential when becomes equal to the energy of the lowest energy state.

Effective widths of boson gas confined in a harmonic rotating trap
TL;DR: In this paper, the radial and axial square radii (effective widths) of a rapidly rotating boson gas were evaluated and a modified semiclassical approximation was suggested.

Theory of Bose-Einstein condensation in trapped gases
TL;DR: In this article, the authors reviewed the Bose-Einstein condensation of dilute gases in traps from a theoretical perspective and provided a framework to understand the main features of the condensation and role of interactions between particles.

Quantum Phase Transition From a Superfluid to a Mott Insulator in a Gas of Ultracold Atoms
TL;DR: This work observes a quantum phase transition in a Bose–Einstein condensate with repulsive interactions, held in a three-dimensional optical lattice potential, and can induce reversible changes between the two ground states of the system.

TL;DR: A theoretical prediction of the momentum distribution is made based on an approach in which trapped bosons acquire fermionic properties, finding that it agrees closely with the measured distribution.

Observation of a one-dimensional Tonks-Girardeau gas.
TL;DR: The observation of a one-dimensional (1D) Tonks-Girardeau (TG) gas of bosons moving freely in 1D, where the gas bosons are strongly interacting, they behave very much like noninteracting fermions.

TL;DR: 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.
