我们证明了AdS5 × T1,1中的某些经典弦组态是混沌的.这就否定地回答了弦在这种背景下的可积性问题。我们考虑一个位于AdS 5中心的弦,它绕着两个T1,1的圆。相应的动力系统等价于两个耦合的引力摆,并允许一个非常直观的理解。通过系统地分析KAM定理的工作原理,我们找到了混沌行为的确凿证据。我们还表明,最大的李雅普诺夫指数是积极的。
We show that certain classical string configurations in AdS 5× T 1, 1 are chaotic. This answers the question of integrability of string on such backgrounds in the negative. We consider a string localized in the center of AdS 5 that winds around two circles of T 1, 1. The corresponding dynamical system is equivalent to two coupled gravitational pendula and allows a very intuitive understanding. We find conclusive evidence of chaotic behavior by systematically analyzing the workings of the KAM theorem. We also show that the largest Lyapunov exponent is positive.
