Existence and stability of discrete intersite bright solitons in Bose Einstein condensates in parabolic trapped optical lattices

Ramesh Kumar, U. Singh, O. P. Swami +2 more

We consider intersite discrete bright solitons in one-dimensional Bose-Einstein condensate in parabolic trapped optical lattice. Analytical and numerical calculations are performed to determine the existence and stability of bright solitons. Analysis is based on continuous Gross-Pitaevskii equation and discrete nonlinear Schrodinger equation. It is observed that the strength of external magnetic trap can change the stability of bright solitons. Stability windows of bright solitons are presented and stability approximations are derived using perturbation theory, with their numerical results.

Dynamical formation of bright solitons in the collapse of Bose-Einstein condensates

Beata J. Dąbrowska-Wüster, Sebastian Wüster, Matthew J. Davis

We model the formation of bright atomic solitons due to collapse of Bose-Einstein condensates with attractive interactions reported by S. L. Cornish et al., [Phys. Rev. Lett. 96 170401 (2006)] in a realistic three dimensional situation. We show that mean-field theory does not adequately explain the experiment, while the inclusion of quantum fluctuations gives rise to bright soliton formation at the appropriate time scales. The solitons are produced either in-phase or out-of-phase and their number increases with the strength of the attractive interaction.
