经典统计力学中非平衡态Stationary States的指数收敛

Exponential Convergence to Non-Equilibrium Stationary States in Classical Statistical Mechanics

Luc Rey-Bellet, Lawrence E. Thomas

摘要:

我们继续研究一个模型的热传导组成的一个链的非线性振子耦合到两个哈密顿热库在不同的温度。我们建立了链动力学的Liapunov函数的存在性,并用它来显示指数快速收敛的动力学到一个独特的稳态。成分的证明是减少的无限维动力学的有限维随机过程,以及在链的非谐振子的能量传播的约束。

英文摘要:

We continue the study of a model for heat conduction consisting of a chain of non-linear oscillators coupled to two Hamiltonian heat reservoirs at different temperatures. We establish existence of a Liapunov function for the chain dynamics and use it to show exponentially fast convergence of the dynamics to a unique stationary state. Ingredients of the proof are the reduction of the infinite dimensional dynamics to a finite-dimensional stochastic process as well as a bound on the propagation of energy in chains of anharmonic oscillators.
