Both the stationary and time evolution problems were analyzed using this approach. The ground state stationary wave functions were found to be sharply peaked near the origin for attractive interatomic interaction for larger nonlinearity while for a repulsive interatomic interaction the wave function extends over a larger region of space.567041-567049engAtomic physicsBoundary conditionsLattice vibrationsLow temperature effectsMathematical modelsOscillationsQuantum electronicsBose-Einstein condensation (BEC)Gross-Pitaevskii equationCondensationNumerical study of the coupled time-dependent Gross-Pitaevskii equation: Application to Bose-Einstein condensationArtigo10.1103/PhysRevE.63.056704WOS:000168730800097Acesso aberto2-s2.0-00353335572-s2.0-0035333557.pdf8031087349809439
