李雅普诺夫指数的发散涨落

Diverging fluctuations of the Lyapunov exponents

Diego Pazo, Juan M. Lopez, Antonio Politi

摘要:

我们表明,在一般的一维哈密顿晶格的扩散系数的最大李雅普诺夫指数发散的热力学极限。我们追溯到与流体动力学模式的演变相关的长程相关性。在正常热传输的情况下,发散甚至更强,导致通常的单函数Family-Vicsek标度系数的崩溃。在存在适当相关的背景噪声的情况下,在粗糙界面的演变中预计会出现类似的情况。

英文摘要:

We show that in generic one-dimensional Hamiltonian lattices the diffusion coefficient of the maximum Lyapunov exponent diverges in the thermodynamic limit. We trace this back to the long-range correlations associated with the evolution of the hydrodynamic modes. In the case of normal heat transport, the divergence is even stronger, leading to the breakdown of the usual single-function Family-Vicsek scaling ansatz. A similar scenario is expected to arise in the evolution of rough interfaces in the presence of a suitably correlated background noise.
