| 摘 要： | 探索了新激光驻波势中两分量波色-爱因斯坦凝聚(BEC)的非定态精确解,并对原子相互作用强度α12≠α11≠α22和α12=α11=α22=α这2种情况都作了讨论.发现对于原子相互作用强度α12≠α11≠α22,这2个分量的波函数是相似的,且2个分量在单个空间周期的粒子数要满足一定关系,而对于α12=α11=α22=α,这2个分量的波函数可能不同,且粒子数间没有限制关系.

| Abstract: | The authors investigated the exact non-stationary solutions for a two-component BEC system confined in an external potential constructed by a optical lattice potential and a optical standing wave.The cases of the interaction strengths are considered.The authors find that the two-component BEC has different properties for the two cases. |
