One-dimensional trapped atoms: critical coupling parameter and critical number of particles
(SPRINGER, 2010)
In this paper we consider the case of a Bose gas in low dimension in order to illustrate the applicability of a method that allows us to construct analytical relations, valid for a broad range of coupling parameters, for ...
The critical number of atoms in an attractive Bose-Einstein condensate on optical plus harmonic traps
(Iop Publishing Ltd, 2003-07-14)
The stability of an attractive Bose-Einstein condensate on a joint one-dimensional optical lattice and an axially symmetrical harmonic trap is studied using the numerical solution of the time-dependent mean-field ...

Mixing-demixing in a trapped degenerate fermion-fermion mixture
(2006-05-11)
We use a time-dependent dynamical mean-field-hydrodynamic model to study mixing-demixing in a degenerate fermion-fermion mixture (DFFM). It is demonstrated that with the increase of interspecies repulsion and/or trapping ...

Critical numbers of attractive Bose-Einstein condensed atoms in asymmetric traps
(2002-01-01)
The recent Bose-Einstein condensation of ultracold atoms with attractive interactions led us to consider the possibility of probing the stability of its ground state in arbitrary three-dimensional harmonic traps. We performed ...
Mean-field model for Josephson oscillation in a Bose-Einstein condensate on an one-dimensional optical trap
(Springer, 2003-08-01)
Using the axially-symmetric time-dependent Gross-Pitaevskii equation we study the phase coherence in a repulsive Bose-Einstein condensate (BEC) trapped by a harmonic and an one-dimensional optical lattice potential to ...
