中文摘要：
文章讨论了对称三势阱中散射长度周期变化下玻色爱因斯坦凝聚体的量子隧穿特性和自俘获现象,通过三模近似来处理含三体项的GP方程.研究表明,这个体系的隧穿动力学可以被周期的散射长度有效的调节,且数值结果展示了在中频调制时,系统会在自俘获的过程中出现共振现象,而在低频、高频时会出现非物理的内爆现象,即粒子的长期行为不可预言.
英文摘要：
In this paper,we discussed the macroscopic quantum tunneling and self-trapping phenomenas in triplewell trapped Bose-Einstein condensates（BECs） which scattering length is periodicly modulated.Using threemode approximation,three coupled Gross-Pitaevskii equations（GPEs） are modified to describe the dynamics of the system.The corresponding numerical results show that this system of the tunneling dynamics can be adjusted by scattering length,and the numerical results show in the intermediate frequency modulation,the system will appear resonance phenomenon in the process of self trapping,non-physical burst phenomenon will appear in low frequency and high frequency,the long-term behavior of particles can not be predicted.
