随机矩阵理论对混沌系统周期轨道的约束

Constraint on periodic orbits of chaotic systems given by Random Matrix Theory

Alejandro G. Monastra

摘要:

考虑到谱函数的涨落,证明了如果混沌系统满足Bohigas-Gianonni-Schmit(BGS)猜想,将其谱统计与随机矩阵的谱统计联系起来,那么借助于Gutzwiller迹公式,经典周期轨道的不稳定性受到约束.特别是对于二维混沌系统,每个周期轨道的李雅普诺夫指数$λ_p$应该大于一个最小值$λ_{\text{min}} \geq 0.850738$。这为一个系统完全混沌或BGS猜想的失败提供了新的约束。

英文摘要:

Considering the fluctuations of spectral functions, we prove that if chaotic systems fulfill the Bohigas-Gianonni-Schmit (BGS) conjecture, which relates their spectral statistics to that of random matrices, therefore by virtue of Gutzwiller trace formula, the instability of classical periodic orbits is constrained. In particular for two-dimensional chaotic systems, the Lyapunov exponent $λ_p$ of each periodic orbit $p$ should be bigger than a minimum value $λ_{\text{min}} \geq 0.850738$. This opens the possibility of new constraints for a system to be fully chaotic, or the failure of the BGS conjecture.
