利用辅助控制维持经典非平衡分布的熵产生的信息论界

Information-theoretic bound on the entropy production to maintain a classical nonequilibrium distribution using ancillary control

Jordan M. Horowitz, Jeremy L. England

摘要:

有许多功能的情况下,它是可取的,以维持一个介观系统在一个非平衡状态。然而,这种控制需要固有的能量耗散。在这篇文章中,我们统一和扩展了一些工作的最小能量成本,以维持一个介观系统在一个规定的非平衡分布,使用辅助控制。对于各种控制机制,我们发现,所需的最小量的能量耗散可以被铸造作为一个信息理论的措施之间的目标非平衡态和基本的平衡分布的可扩展性。这项工作提供了定量的洞察力的直观想法,需要更多的能量来维持一个系统远离平衡。

英文摘要:

There are many functional contexts where it is desirable to maintain a mesoscopic system in a nonequilibrium state. However, such control requires an inherent energy dissipation. In this article, we unify and extend a number of works on the minimum energetic cost to maintain a mesoscopic system in a prescribed nonequilibrium distribution using ancillary control. For a variety of control mechanisms, we find that the minimum amount of energy dissipation necessary can be cast as an information-theoretic measure of distinguishability between the target nonequilibrium state and the underlying equilibrium distribution. This work offers quantitative insight into the intuitive idea that more energy is needed to maintain a system farther from equilibrium.
