我们探讨了非平衡定态的热力学关系与数值实验驱动的格子气。在操作上定义的压力和化学势的驱动晶格气体,我们确认数值的有效性的可积性条件(麦克斯韦关系)的两个量的值不同于那些平衡系统。这意味着我们可以为所考虑的非平衡定态构造一个自由能函数。我们还调查了与此自由能函数的波动关系。我们的结果表明,即使在非平衡稳态下,压缩性也可以用密度涨落来表示。
We explore thermodynamic relations in nonequilibrium steady states with numerical experiments on a driven lattice gas. After operationally defining the pressure and chemical potential in the driven lattice gas, we confirm numerically the validity of the integrability condition (the Maxwell relation) for the two quantities whose values differ from those for an equilibrium system. This implies that a free-energy function can be constructed for the nonequilibrium steady state that we consider. We also investigate a fluctuation relation associated with this free-energy function. Our result suggests that the compressibility can be expressed in terms of density fluctuations even in nonequilibrium steady states.
