| Abstract: | By using of the invariant theory, we have studied phase of a Bose-Einstein condensate in a double-well potential modulated
periodically in time when the on-site interaction energy of a single pair of bosons occupying the same well equals the collision
energy between two condensates, the dynamical and geometric phases are presented respectively. The Aharonov-Anandan phase
is also obtained in the case of the cyclical evolution.
