广义Langevin方程的非遍历解

Nonergodic solutions of the generalized Langevin equation

A. V. Plyukhin

摘要:

众所周知,在超线性扩散的制度,其特征在于零积分摩擦(消失积分的记忆功能),广义朗之万方程可能有非遍历的解决方案,不放松到平衡值。它表明,该方程可能有非遍历(非平稳)的解决方案,即使记忆函数的积分是有限的和扩散是正常的。

英文摘要:

It is known that in the regime of superlinear diffusion, characterized by zero integral friction (vanishing integral of the memory function), the generalized Langevin equation may have non-ergodic solutions which do not relax to equilibrium values. It is shown that the equation may have non-ergodic (non-stationary) solutions even if the integral of the memory function is finite and diffusion is normal.
