Abstract
The dynamics of the composition of uniform Bose condensates involving two s pecies capable of reciprocal interconversion is treated in terms of a colle ctive quasi-spin model. This collective model quickly reduces to classical form towards the thermodynamic limit. Quantum solutions are easily obtained numerically short of this limit which give insight into the dynamically re levant correlation processes. (C) 2001 Published by Elsevier Science B.V.
