摘　　要：运用直接微扰方法求得一维斜光格子势阱中囚禁Bose-Einstein凝聚体的混沌解,并绘出和研究了该系统的动力学相图。理论解析和相应的数值结果都表明此Bose-Einstein凝聚体系统的混沌行为。通过改变入射激光的波长或调节系统参数,可以控制Bose-Einstein凝聚体的混沌。Using the direct perturbation technique, a general unstable chaotic solution was obtained of the Bose-Einstein condensates trapped in one-dimensional tilted optical lattice potential. The dynamical phase diagram of this system was studied. Theoretical analysis results and the corresponding numerical results showed the chaotic behavior of the system. It was found that Bose-Einstein condensate chaos could be controlled by changing the wave length of the incident laser light or adjusting the system parameters.
