| Abstract: | The spatial structure of a Bose-Einstein condensate (BEC) loaded
into an optical lattice potential is investigated and the spatially
chaotic distributions of the condensates are revealed. A method of
chaos control with linear feedback is presented in this paper. By using the method, we propose a scheme of controlling chaotic behavior in a BEC with atomic mirrors. The results of the computer simulation show that controlling the chaos into the stable states could be realized by adjusting the coefficient of feedback only if
the maximum Lyapunov exponent of the system is negative. |
