摘要：
Entanglement of spin and position variables produced by spatially inhomogeneous magnetic fields of Stern-Gerlach type acting on spinor Bose-Einstein condensates may lead to interference effects at the level of one-boson densities. A model is worked out for these effects which is amenable to analytical calculation for Gaussian-shaped condensates. The resulting interference effects are sensitive to the spin polarization properties of the condensate.
