We review the theory of vortices in trapped dilute Bose-Einstein condensates and compare
theoretical predictions with existing experiments. Mean-field theory based on the time …

This article reviews recent investigations on the phenomenon of Bose-Einstein
condensation of dilute gases. Since the experimental observation of quantum degeneracy in …

Using a focused laser beam we stir a Bose-Einstein condensate of 87 Rb confined in a
magnetic trap and observe the formation of a vortex for a stirring frequency exceeding a …

We have created vortices in two-component Bose-Einstein condensates. The vortex state
was created through a coherent process involving the spatial and temporal control of …

The aim of this introductory article is two-fold. First, we aim to offer a general introduction to
the theme of Bose-Einstein condensates, and briefly discuss the evolution of a number of …

We have investigated the formation of vortices by rotating the purely magnetic potential
confining a Bose-Einstein condensate. We modified the bias field of an axially symmetric …

We study the quadrupole oscillation of a Bose-Einstein condensate of 87 Rb atoms confined
in an axisymmetric magnetic trap, after it has been stirred by an auxiliary laser beam. The …

Abstract Observations of Bose–Einstein condensates—macroscopic populations of ultracold
atoms occupying a single quantum state—in dilute alkali-metal and hydrogen gases have …

Dark soliton states of Bose-Einstein condensates in harmonic traps are studied both
analytically and computationally by the direct solution of the Gross-Pitaevskii equation in …

We demonstrate numerically the efficient generation of vortices in Bose-Einstein
condensates (BECs) by using a “phase imprinting” method. The method consists of passing …
