微不对称双阱中二元玻色-爱因斯坦凝聚体介观叠加态的产生
Generation of mesoscopic superpositions of a binary Bose-Einstein condensate in a slightly asymmetric double well
摘要：
先前的出版物[Europhysics Letters 78，10009（2007）]建议在完全对称的条件下在双阱中相干地产生双组分玻色-爱因斯坦凝聚体的介观叠加。然而，已经很小的不对称性可以破坏基态的纠缠特性。然而，即使在更现实的条件下，该计划被证明数值生成介观叠加。
英文摘要：
A previous publication [Europhysics Letters 78, 10009 (2007)] suggested to coherently generate mesoscopic superpositions of a two-component Bose-Einstein condensate in a double well under perfectly symmetric conditions. However, already tiny asymmetries can destroy the entanglement properties of the ground state. Nevertheless, even under more realistic conditions, the scheme is demonstrated numerically to generate mesoscopic superpositions.
