    • The interaction with the noncondensed component has very little effect on the expansion of the condensate and we find that the result of the split operator technique can be very precisely represented with an analytical model. We start with the method of Castin and Dum for calculating the condensate expansion with no noncondensed cloud interaction (see CASTIN Y. and DUM R., Phys. Rev. Lett., 77 (1996) 5315). We introduce a finite healing length at the condensate surface (DALFOVO F., PITAEVSKII L. and STRINGARI S., Phys. Rev. A, 54 (1996) 4213) by replacing the first derivative of the Castin-Dum condensate wave function with a product of that derivative and a Fermi function centered at the surface. Since the density profile in the interface region is very sensitive to the exact shape of the condensate surface, it is important to include this smoothing of the condensate density at the surface.
