摘要：

<正> The spatial structure of a Bose-Einstein condensate (BEC) loaded into an optical lattice potential isinvestigated and the spatially chaotic distributions of the condensates are revealed.A method of chaos control withlinear feedback is presented in this paper.By using the method,we propose a scheme of controlling chaotic behaviorin a BEG with atomic mirrors.The results of the computer simulation show that controlling the chaos into the stablestates could be realized by adjusting the coefficient of feedback only if the maximum Lyapunov exponent of the systemis negative.
