Critical numbers of attractive Bose-Einstein condensed atoms in asymmetric traps
(2002-10-01)
A quantitative analysis of the critical number of attractive Bose-Einstein condensed atoms in asymmetric traps was studied. The Gross-Pitaevskii (GP) formalism for an atomic system with arbitrary nonspherically symmetric ...

Chaotic oscillation in an attractive Bose-Einstein condensate under an impulsive force
(2002-04-01)
The chaotic oscillation in an attractive Bose-Einstein condensate (BEC) under an impulsive force was discussed using mean-field Gross-Pitaevskii (GP) equation. It was found that sustained chaotic oscillation resulted in a ...
Solitons in a Spin-Orbit-Coupled Spin-1 Bose-Einstein Condensate
(2021-04-01)
After the pioneering studies on spinor Bose-Einstein condensate (BEC) and after the realization of spin-orbit (SO) coupling in a spinor BEC of 87Rb and 23Na atoms, it is now realized that an SO-coupled BEC may reveal new ...
Dissipation-managed soliton in a quasi-one-dimensional Bose-Einstein condensate
(Iop Publishing Ltd, 2006-11-01)
We use the time-dependent mean-field Cross-Pitaevskii equation to study the formation of a dynamically-stabilized dissipation managed bright soliton in a quasi-one dimensional Bose-Einstein condensate (BEC). Because of ...

Phase separation in a spin-orbit-coupled Bose-Einstein condensate
(2014-10-20)
We study a spin-orbit (SO)-coupled hyperfine spin-1 Bose-Einstein condensate (BEC) in a quasi-one-dimensional trap. For an SO-coupled BEC in a one-dimensional box, we show that in the absence of the Rabi term, any nonzero ...
Oscilações não-lineares em condensados de Bose-Einstein
(Universidade Estadual Paulista (Unesp), 2004-10)
Estudamos as oscilações não-lineares de um condensado de Bose-Einstein em três dimensões numa armadilha com simetria esférica e com comprimento de espalhamento periódico no tempo. Usamos o método variacional dependente do ...
Effect of an impulsive force on vortices in a rotating Bose-Einstein condensate
(Elsevier B.V., 2002-08-26)
The effects of a sudden increase and decrease of the interatomic interaction and harmonic-oscillator trapping potential on vortices in a quasi two-dimensional rotating Bose-Einstein condensate are investigated using the ...
