摘要：
We study a superfluid Bose system with single-particle and pair condensates using a nonperturbative approach. The self-consistency equations for two order parameters are obtained from the principle of maximum entropy. They are analyzed numerically at zero temperature for dilute (gases of alkali-metal atoms) and dense (superfluid He-4) systems. It is shown that the pair condensate fraction is negligible for dilute systems and becomes dominant for dense systems.
