In a system of interactingbosons (in the subspace where the total spin in thedirection is vanishing), we prove inequalities for the ground state expectation value of the density of spin-0 bosons. The inequalities imply that the ground state possesses “polar” or “antiferromagnetic” order when the quadratic Zeeman termis large enough. In the low density limit, the inequalities establish the existence of a sharp transition atwhenis varied.
