Abstract
We study the stability of two-component Bose-Einstein condensates under mag netic traps. Extending the variational method, we investigate the stable an d unstable conditions as functions of the particle numbers and the s-wave s cattering lengths. We find that interaction between the different species o f atoms (simply, interspecies interaction) has significant effects on the s tability of each condensate. (C) 2000 Elsevier Science B.V.
