Abstract
The two-component Bose-Einstein condensate exhibits oscillations in the ind ividual particle number when the two species an coupled by a Josephson coup ling. We present the results of numerical calculations based on coupled Gro ss-Pitaevskii equations, and compare the results with an approximate analyt ic theory. The small amplitude limit reproduces the conventional results, b ut the large signal regime offers some features characteristic of the trapp ed systems. [S1050-2937(99)09005-8].
