Abstract: | The stable nonlinear transport of the Bose--Einstein condensates
through a double barrier potential in a waveguide is studied. By
using the direct perturbation method we have obtained a perturbed
solution of Gross--Pitaevskii equation. Theoretical analysis reveals
that this perturbed solution is a stable periodic solution, which
shows that the transport of Bose--Einstein condensed atoms in this
system is a stable nonlinear transport. The corresponding numerical
results are in good agreement with the theoretical analytical
results. |
