    "abstract": "A mean-density description of spatially-inhomogeneous Bose-condensed gases\nbased on Bogoliubov\u0027s method is introduced. The description assumes only a\nlarge mean atomic density and so remains valid when the mean field collapses\ndue to phase diffusion. A spread in the number of particles in the condensate\nis shown to lead to an anomalous coupling between the condensate and excited\nmodes. This coupling is due to the dependence of the condensate spatial\nwavefunction on particle number and it could, in principle, be used for\nreducing particle fluctuations in the condensate.",
