Two-dimensional bright and dark-in-bright dipolar Bose-Einstein condensate solitons on a one-dimensional optical lattice
(2016-08-01)
We study the statics and dynamics of anisotropic, stable, bright and dark-in-bright dipolar quasi-two-dimensional Bose-Einstein condensate (BEC) solitons on a one-dimensional (1D) optical-lattice (OL) potential. These ...
Dark-soliton collisions in a toroidal Bose-Einstein condensate
(American Physical Society, 2016-02)
We study the dynamics of two gray solitons in a Bose-Einstein condensate confined by a toroidal trap with a tight confinement in the radial direction. Gross-Pitaevskii simulations show that solitons can be long-living ...

Stable and mobile two-dimensional dipolar ring-dark-in-bright Bose-Einstein condensate soliton
(2016-03-01)
We demonstrate robust, stable, mobile two-dimensional (2D) dipolar ring-dark-in-bright (RDB) Bose-Einstein condensate (BEC) solitons for repulsive contact interaction, subject to a harmonic trap along the y direction ...
Stable, mobile, dark-in-bright, dipolar Bose-Einstein-condensate solitons
(2014-04-23)
We demonstrate robust, stable, mobile, quasi-one-dimensional, dark-in-bright dipolar Bose-Einstein-condensate (BEC) solitons with a notch in the central plane formed due to dipolar interaction for repulsive contact ...
Stable, mobile, dark-in-bright, dipolar Bose-Einstein-condensate solitons
(Amer Physical Soc, 2014-04-23)
We demonstrate robust, stable, mobile, quasi-one-dimensional, dark-in-bright dipolar Bose-Einsteincondensate (BEC) solitons with a notch in the central plane formed due to dipolar interaction for repulsive contact interaction. ...
Black soliton in a quasi-one-dimensional trapped fermion-fermion mixture
(Wiley-Blackwell, 2006-12-01)
Employing a time dependent mean-field-hydrodynamic model we study the generation of black solitons in a degenerate fermion-fermion mixture in a cigar-shaped geometry using variational and numerical solutions. The black ...
