Popis:	We study relative number squeezing of a Bose-Einstein condensate in the Bogoliubov vacuum, using the stochastic truncated Wigner method for confined, freely expanding and phase modulated condensates by determining the number difference variance between left and right binned number operators. We show that this variance lies below the shot-noise limit for experimentally relevant parameters.
