Abstract
Using an inverse scattering method, we find the exact bright and dark soliton solutions of the nonlinear Gross-Pitaevskii equation with external potentials. We also investigate the nonlinear excitation of a Bose-Einstein condensate under external fields. We reveal an efficient means of controlling solitons in a Bose-Einstein condensate for use in future experiments.
