Interaction-induced dynamical phase locking of Bose-Einstein condensates
Abstract
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 g12(1)1/3 throughout the Josephson interaction regime, as evident from a semiclassical picture. Other types of incoherent preparation yield qualitatively different coherence dynamics.
