Interaction-induced dynamical phase locking of Bose-Einstein condensates Academic Article uri icon


  • We show that interactions result in the emergence of a definite relative phase between two initially incoherent Bose-Einstein condensates. The many-realization interference fringe visibility is universal at ${g}_{12}^{(1)}\ensuremath{\sim}1/3$ throughout the Josephson interaction regime as evident from a semiclassical picture. Other types of incoherent preparation yield qualitatively different coherence dynamics.
