振子网络的非平衡定态

Non-Equilibrium Steady States for Networks of Oscillators

Noé Cuneo, Jean-Pierre Eckmann, Martin Hairer, Luc Rey-Bellet

摘要:

由谐波和非谐波弹簧连接的振荡器(质量)链的非平衡稳态,并与不同温度下的热浴相互作用,一直是几项研究的主题。在本文中,我们将展示一些结果如何扩展到更复杂的网络。我们建立了非平衡稳态的存在性和唯一性,并表明系统以指数速率收敛到非平衡稳态。参数是基于在无穷远的潜力的可控性和条件。

英文摘要:

Non-equilibrium steady states for chains of oscillators (masses) connected by harmonic and anharmonic springs and interacting with heat baths at different temperatures have been the subject of several studies. In this paper, we show how some of the results extend to more complicated networks. We establish the existence and uniqueness of the non-equilibrium steady state, and show that the system converges to it at an exponential rate. The arguments are based on controllability and conditions on the potentials at infinity.
