CONTROLLING CHAOS IN THE BOSE-EINSTEIN CONDENSATE
Cong F., Pang S., Hua H., Tong S., Wang Z.
Received: July 26, 2011
The spatial structure of the Bose-Einstein condensate (BEC) is investigated and spatially chaotic distributions of the condensates are revealed. By means of changing the s-wave scattering length with a Feshbach resonance, the chaotic behavior can be well controlled to enter into periodicity. Numerical simulation shows that there are different periodic orbits according to different s-wave scattering lengths only if the Lyapunov exponent of the system is negative.
