Localization of a Bose-Einstein condensate in a bichromatic optical lattice
(2009-08-11)
By direct numerical simulation of the time-dependent Gross-Pitaevskii equation, we study different aspects of the localization of a noninteracting ideal Bose-Einstein condensate (BEC) in a one-dimensional bichromatic ...

Bright solitons in Bose-Einstein condensates with field-induced dipole moments
(Iop Publishing Ltd, 2014-04-14)
We introduce an effectively one-dimensional model of a bosonic gas of particles carrying collinear dipole moments which are induced by an external polarizing field with the strength periodically modulated along the coordinate, ...
Dipolar Bose-Einstein condensate soliton on a two-dimensional optical lattice
(Elsevier B.V., 2012-06-25)
Using a three-dimensional mean-field model we study one-dimensional dipolar Bose-Einstein condensate (BEC) solitons on a weak two-dimensional (2D) square and triangular optical lattice (OL) potentials placed perpendicular ...

Winding-number dependence of Bose-Einstein condensates in a ring-shaped lattice
(American Physical Society, 2011-01)
We study the winding-number dependence of the stationary states of a Bose-Einstein condensate in a ring-shaped lattice. The system is obtained by confining atoms in a toroidal trap with equally spaced radial barriers. We ...
Multimode model for an atomic Bose-Einstein condensate in a ring-shaped optical lattice
(American Physical Society, 2013-07)
We study the population dynamics of a ring-shaped optical lattice with a high number of particles per site and a low (less than ten) number of wells. Using a localized on-site basis defined in terms of stationary states, ...
Loss of superfluidity in a Bose-Einstein condensate on an optical lattice via a novel classical phase transition
(Elsevier B.V., 2003-03-03)
We predict the loss of superfluidity in a Bose-Einstein condensate (BEC) trapped in a combined optical and axially-symmetric harmonic potentials during a resonant collective excitation initiated by a periodic modulation ...
