Intrinsic and extrinsic thermodynamics for stochastic population processes with multi-level large-deviation structure

Eric Smith

摘要:

一组核心功能的热力学描述的本质,从大偏差的时间尺度层次的系统中的属性,但这是\emph{not}依赖于守恒定律或微观可逆性的基板托管的过程。最基本的元素是宏观态与大偏差熵的概念,以及相互作用的子系统之间对不可逆性的贡献的分解,这是经典和随机热力学中依赖热概念的起源。一个自然的分解是存在的,到一个相对熵和内务熵率,分别定义的\textit{intensive}热力学系统和\textit{extensive}热力学向量嵌入系统在其上下文中。这两个密集和广泛的组件是功能的Hartley信息的瞬时系统定态,这是信息\emph{about}的联合效应的系统过程的贡献不可逆性。结果推导出随机化学反应网络,包括勒让德对偶的管家熵率,完全不可逆的过程中,在平等的基础上与那些在相反的限制详细的平衡。这项工作的目的是鼓励发展固有的热力学描述的规则为基础的系统和生活状态,这是不被视为还原解释热流。

英文摘要:

A set of core features is set forth as the essence of a thermodynamic description, which derive from large-deviation properties in systems with hierarchies of timescales, but which are \emph{not} dependent upon conservation laws or microscopic reversibility in the substrate hosting the process. The most fundamental elements are the concept of a macrostate in relation to the large-deviation entropy, and the decomposition of contributions to irreversibility among interacting subsystems, which is the origin of the dependence on a concept of heat in both classical and stochastic thermodynamics. A natural decomposition is shown to exist, into a relative entropy and a housekeeping entropy rate, which define respectively the \textit{intensive} thermodynamics of a system and an \textit{extensive} thermodynamic vector embedding the system in its context. Both intensive and extensive components are functions of Hartley information of the momentary system stationary state, which is information \emph{about} the joint effect of system processes on its contribution to irreversibility. Results are derived for stochastic Chemical Reaction Networks, including a Legendre duality for the housekeeping entropy rate to thermodynamically characterize fully-irreversible processes on an equal footing with those at the opposite limit of detailed-balance. The work is meant to encourage development of inherent thermodynamic descriptions for rule-based systems and the living state, which are not conceived as reductive explanations to heat flows.
