文章中着重研究在三势阱中的凝聚体所受到的非弹性碰撞相互作用,考虑有三体复合耗散和原子填充时三势阱中玻色-爱因斯坦凝聚体动力学性质,研究了三势阱中玻色-爱因斯坦凝聚体系的自囚禁与宏观量子遂穿问题,用数值分析和解析推导的方法,发现自俘获和宏观量子隧穿现,另外,在自俘获和宏观量子隧穿进程中发现了量子拍现象,并对这些现象给出合理的解释。
文章中著重研究在三勢阱中的凝聚體所受到的非彈性踫撞相互作用,攷慮有三體複閤耗散和原子填充時三勢阱中玻色-愛因斯坦凝聚體動力學性質,研究瞭三勢阱中玻色-愛因斯坦凝聚體繫的自囚禁與宏觀量子遂穿問題,用數值分析和解析推導的方法,髮現自俘穫和宏觀量子隧穿現,另外,在自俘穫和宏觀量子隧穿進程中髮現瞭量子拍現象,併對這些現象給齣閤理的解釋。

We study the three-body interaction in triple-well trapped Bose-Einstein Condensates. We investigate the stability in triple-well trapped Bose-Einstein condensates with atoms feeding and loss effects, self-trapping phenomenon and macroscopic tunnelling problem in triple-well trapped Bose-Einstein condensates are investigated. We observe the quantum beating phenomenon during the self-trapping and quantum tunnelling. At last,reasonable interpretations for these findings are given with numerical and analytical method.
