Abstract

The loss of atoms from the condensate wave packets due to the elastic scattering mechanism was described by using the appropriate momentum dependence of the nonlinear coupling constant in the Gross-Pitaevskii equation (GPE) and using a newly developed slowly varying envelope approximation (SVEA). By using the GPE and SVEA, the effect of elastic scattering losses on the condensate dynamics was efficiently clarified, even in single spin component systems.
