Phys. Rev. A 64, 053613 (2001) [6 pages]Macroscopic quantum superposition states in Bose-Einstein condensates: Decoherence and many modesReceived 11 June 2001; published 12 October 2001 We investigate the feasibility of a particular scheme for generating macroscopic quantum superposition states in two-species dilute gas Bose-Einstein condensates. The scheme utilizes two-body interactions and Josephson coupling between the species. We report numerical studies that extend a previous two-mode model to include dissipation and extra modes. © 2001 The American Physical Society URL:
