摘要
We consider single-particle coherence and spin squeezing in Bose-Einstein Condensate (BEC) with Josephson-like coupling when the BEC is initially in a coherent spin state. Josephson-like coupling gives vanishing contribution to single-particle coherence and spin squeezing. The stronger squeezing can be achieved by increasing the number of atoms.
