Journal ArticleDOI
Zero-temperature properties of a trapped Bose-condensed gas: Beyond the Thomas-Fermi approximation
TL;DR: In this paper, the leading corrections to the Thomas-Fermi approach to the description of the properties of a magnetically trapped, Bose-condensed cloud of atoms are considered.
Journal ArticleDOI
Multiply quantized vortices in trapped Bose-Einstein condensates
TL;DR: In this paper, the Bose-Einstein condensed gases trapped in power-law and anharmonic potentials are studied and features of the wave function for small and intermediate rotation frequencies are investigated numerically.
Journal ArticleDOI
Hydrodynamic approach to vortex lifetimes in trapped Bose condensates
Emil Lundh,Ping Ao +1 more
TL;DR: In this paper, a vortex in a two-dimensional, harmonically trapped Bose-Einstein condensate at zero temperature is studied, and the effective potential experienced by a vortex at an arbitrary position in the condensates is derived.
Journal ArticleDOI
Vortices in Bose-Einstein-condensed atomic clouds
TL;DR: In this paper, the authors used both analytical and numerical methods to solve the time-dependent Gross-Pitaevskii equation for the case when a cloud of atoms containing a vortex is released from a trap.
Journal ArticleDOI
Ratchet effect for cold atoms in an optical lattice.
Emil Lundh,Mats Wallin +1 more
TL;DR: In this article, the possibility of realizing a directed current for a quantum particle in a flashing asymmetric potential was investigated, and it was found that quantum resonances, where the value of the effective Planck constant is equal to an integer or half-integer multiple of pi, give rise to the directed current.
