摘要：
It is predicted that for the case of off-resonant coupling between two collective excitations of a Bose-Einstein condensed gas (BEC), the two modes may exhibit the antibunching effect, Correlation between them is nonclassical, which means that there exists a violation of the Cauchy-Schwartz inequality.
