The sandwich type condensate density profiles, in this case, acquire a side-by-side density profile configuration. We use Hartree-Fock-Bogoliubov theory with Popov approximation to examine the mode evolution and density profiles for these phase transitions at T = 0.falseArticlehttps://arxiv.org/pdf/1501.0359019516401571-5751 April 20156arJournal6
