论文摘要

一方面,热力学工作提取过程的消散热量上限非预测性信息,该信息与该系统相关的系统对其环境进行了编码。因此,可以从高热力学效率的压力的角度来理解新兴的信息处理能力。另一方面,热力学的第二定律在复杂,自组织的耗散结构的出现中起着至关重要的作用。这种结构在热力学上受到青睐,因为它们可以消散自由能储层,否则就无法使用。因此,它们允许封闭的系统从一个元稳定状态移动到另一个元熵的元稳定状态。本文将争辩说,这两种观点并不矛盾,但是它们的组合允许了解从简单的自组织耗散结构到复杂的信息处理系统的过渡。如果耗散结构所需的效率以从自由能的通道流量以保持其自身结构的高度收获足够的工作,则该系统具有预测性的驱动力。尽管如此,与没有任何耗散结构的情况相比,这种耗散系统的存在是热力学上的。由于出现了耗散系统的层次结构,该系统本身就是可以消散的非平衡结构,因此这种驱动会自然发展,因为这个层次结构越来越远离最初的驾驶不平衡。

On the one hand, the dissipated heat of a thermodynamic work extraction process upper bounds the non-predictive information, which the associated system encodes about its environment. Thus, emergent information processing capabilities can be understood from the perspective of a pressure towards high thermodynamic efficiency. On the other hand, the second law of thermodynamics plays a crucial role in the emergence of complex, self-organising dissipative structures. Such structures are thermodynamically favoured, because they can dissipate free energy reservoirs, which would not be accessible otherwise. Thereby, they allow a closed system to move from one meta-stable state to another meta-stable state of higher entropy. This paper will argue, that these two views are not contradictory, but that their combination allows to understand the transition from simple self-organising dissipative structures to complex information processing systems. If the efficiency required by a dissipative structure to harvest enough work from the channeled flow of free energy to maintain its own structure is high, there is a drive for this system to be predictive. Still, the existence of this dissipative system is thermodynamically favoured, compared to a situation without any dissipative structure. Due to the emergence of a hierarchy of dissipative systems, which by themselves are non-equilibrium structures that can be dissipated, such a drive develops naturally, as one ascends in this hierarchy further and further away from the initial driving disequilibrium.
