Abstract
The macroscopic interference of two Bose condensates released from a d ouble minimum potential has been demonstrated recently [M.R. Andrews e t al., Science 275, 637 (1997)]. In this Letter we show the excellent agreement between those experiments and theoretical predictions based on the nonlinear Schrodinger equation. In addition, the transition fro m interference of coupled condensates, comparable with the Josephson e ffect in superconductors, to the interference of independent Bose cond ensates is studied.
