| 摘 要： | 考虑外部囚禁势阱为光晶格势阱,研究了二元玻色-爱因斯坦凝聚体中亮-亮孤子的动力学行为.结果表明,亮-亮孤子的运动方向和振荡行为可以分别通过调节光晶格势阱的晶格常数和势阱深度来控制.进一步地,亮-亮孤子还可以被局域在光晶格势阱中,并且随着势阱深度的增加,局域孤子会产生分裂行为.

| Abstract: | We have studied the dynamic behavior of bright-bright solitons in two-species Bose-Einstein condensates trapped in an optical lattice. It is shown that the directions of motion and oscillations of the bright-bright solitons can be effectively controlled by adjusting the lattice spacing and height, respectively. Especially, two separated solitons can be localized in the optical lattice, and the fission of each localized soliton is newly observed due to the increase of the lattice height.
