چکیده

1 Abstract — Zusammenfassung We study three-dimensional rapidly rotating Bose-Einstein condensates in a theoretical context. The main results are lower and upper bounds on the Gross-Pitaevskii energy of the dilute Bose gas in the Thomas-Fermi limit. Similar results were already obtained for strongly anharmonic external potentials in 2D [CRDY07b, CY08] and homogeneous external potentials in 2D [CRDY07a] and 3D [BCPY08] whereas we present the treatment of partially anisotropic traps in 3D. Furthermore a complete description and illustration of the Thomas-Fermi density in this limit is given. We also supply the source code for the generation of the illustrations. Wir untersuchen dreidimensionale schnell rotierende Bose-Einstein Kondensate in einem theo-retischen Kontext. Die Hauptresultate sind untere und obere Schranken an die Gross-Pitaevskii Energie des verdünnten Bose Gases im Thomas-Fermi Limes. ¨ Ahnliche Resultate wurden bereits für stark anharmonischë außere Potentiale in 2D [CRDY07b, CY08] und homogenë außere Poten-tiale in 2D [CRDY07a] und 3D [BCPY08] entwickelt wohingegen wir die Betrachtung von teilweise anisotropen Fallen in 3D präsentieren. Weiters geben wir eine komplette Beschreibung und Illustration der Thomas-Fermi Dichte in diesem Grenzwert an. Wir stellen auch den Quelltext zur Erstellung der Illustrationen zur Verfügung.

Local Spin-Gauge Symmetry of the Bose-Einstein Condensates in Atomic Gases.

The Bose-Einstein condensates of alkali atomic gases are spinor fields with local “spin-gauge” symmetry. This symmetry is manifested by a superfluid velocity us (or gauge field) generated by the Berry phase of the spin field. In “static” traps, us splits the degeneracy of the harmonic energy levels, breaks the inversion symmetry of the vortex nucleation frequency Ωc1, and can lead to vortex gro...

N ov 1 99 9 Bose - Einstein condensation in a rotating anisotropic TOP trap

We describe the construction and operation of a time-orbiting potential trap (TOP trap) that has different oscillation frequencies along its three principal axes. These axes can be rotated and we have observed Bose-Einstein condensates of 87 Rb with a rotating ellipsoidal shape. Under these conditions it has been predicted that quantized vortices form and are stable.

Universal solutions for interacting bosons in one-dimensional harmonic traps

We consider systems of interacting bosons confined to one-dimensional harmonic traps. In the limit of perturbatively weak two-body interactions the system exhibits several universal states that are exact solutions for a large class of two-body interactions. These states are closely related to the exact solutions found previously in rotating Bose-Einstein condensates.

Ground states and dynamics of rotating Bose-Einstein condensates

In this paper, we review the mathematical and numerical studies of ground states and dynamics in rotating Bose-Einstein condensates (BEC). We start from the three-dimensional (3D) Gross-Pitaevskii equation (GPE) with an angular momentum rotation term, scale it to obtain a four-parameter model, reduce it to a 2D GPE in the limiting regime of strong anisotropic confinement and present its semicla...

Observation of vortex pinning in Bose-Einstein condensates.

We report the observation of vortex pinning in rotating gaseous Bose-Einstein condensates. Vortices are pinned to columnar pinning sites created by a corotating optical lattice superimposed on the rotating Bose-Einstein condensates. We study the effects of two types of optical lattice: triangular and square. In both geometries we see an orientation locking between the vortex and the optical lat...
