论文摘要
一个非平衡系统的特征是一组热力学力和通量，这些力引起熵产生（EP）。我们表明，这些力和通量具有信息几何结构，这使我们能够将EP分解为来自不同类型的力（线性和非线性）离散系统的贡献。我们专注于过量和家政分解，这将贡献与保守和非保守力量分开。与Hatano-SASA分解不同，我们的家政/过剩条款总是明确的，包括在具有奇数变量和没有稳态的非线性系统的系统中。我们的分解导致远程平衡热力学不确定性关系和速度限制。作为例证，我们在化学振荡器中一个周期所需的时间得出了一种热力学结合。
A nonequilibrium system is characterized by a set of thermodynamic forces and fluxes which give rise to entropy production (EP). We show that these forces and fluxes have an information-geometric structure, which allows us to decompose EP into contributions from different types of forces in general (linear and nonlinear) discrete systems. We focus on the excess and housekeeping decomposition, which separates contributions from conservative and nonconservative forces. Unlike the Hatano-Sasa decomposition, our housekeeping/excess terms are always well-defined, including in systems with odd variables and nonlinear systems without steady states. Our decomposition leads to far-from-equilibrium thermodynamic uncertainty relations and speed limits. As an illustration, we derive a thermodynamic bound on the time necessary for one cycle in a chemical oscillator.
