考虑种内和种间相互作用均为排斥作用,研究了局限于谐振 外部势阱中的二元玻色-爱因斯坦凝聚体中灰-灰和黑-黑孤子的动力学行为. 结果表明:当谐振势阱的轴向囚禁频率为零时,灰-灰和黑-黑孤子均能保持局域稳定;而当轴向囚禁频率不为零时,凝聚体中的原子向势阱中心聚集,发现灰-灰孤子可以转化成亮-亮孤子.

Considering the interspecies and intraspecies interactions as being repulsive, we study the dynamic behaviors of the gray-gray and black-black solitons in two-species Bose-Einstein condensates trapped in the harmonic external potentials. The results show that in the absence of the axial trapping frequencies, both the gray-gray and black-black solitons can keep localization stable. In the presence of the axial trapping frequencies, the gray-gray can be converted into bright-bright solitons.[1] Burger S, Bongs K, Dettmer S, Ertmer W, Sengstock K 1999 Phys. Rev. Lett. 83 5198
