摘要
在周期调制场下,通过对双势阱中费米子数目及相互作用参数的调节,研究了该系统中玻色子的自俘获现象.研究发现,系统中费米子数目及相互作用参数都会影响玻色子的自俘获现象,并且随着相互作用及粒子数目的变化,玻色子的自俘获发生临界现象.
In this paper, we study the self-trapping of a Bose-Fermi mixture in a periodic modulation field by adjusting fermionic number and interaction parameter in a double-well potential. We find that the self-trapping of bosons can be affected by interatomic self-interactionand interspecific interaction parameter. Moreover, we notice that the self-trapping of bosons gives rise to a critical phenomenon with the variation of interaction strength and fermionic number.
