摘要: The two-component Bose-Einstein condensate exhibits oscillations in the individual particle number when two species are coupled by a Josephson coupling. We present results of numerical calculations based on Gross-Pitaevskii equations, and compare with an approximate analytic theory. small amplitude limit reproduces conventional results, but large signal regime offers some features characteristic trapped systems.
