    "abstract": "We calculate the geometric phase associated with the time evolution of the\nwave function of a Bose-Einstein condensate system in a double-well trap by\nusing a model for tunneling between the wells. For a cyclic evolution, this\nphase is shown to be half the solid angle subtended by the evolution of a unit\nvector whose z component and azimuthal angle are given by the population\ndifference and phase difference between the two condensates. For a non-cyclic\nevolution an additional phase term arises. We show that the geometric phase can\nalso be obtained by mapping the tunneling equations onto the equations os a\nspace curve. The importance of a geometric phase in the context of some recent\nexperiments is pointed out.",
