反馈控制的非平衡热力学

Nonequilibrium Thermodynamics of Feedback Control

Takahiro Sagawa, Masahito Ueda

摘要:

建立了经典随机热力学系统反馈控制的一般理论,推广了非平衡态方程如涨落定理和Jarzynski方程在多测量反馈控制下的应用.我们的结果是以前相关工作对一般测量和多热浴情况的概括。所获得的等式涉及表征通过测量或反馈控制的功效获得的信息的附加项。一个广义Szilard引擎和反馈控制棘轮满足派生的等式。

英文摘要:

We establish a general theory of feedback control on classical stochastic thermodynamic systems, and generalize nonequilibrium equalities such as the fluctuation theorem and the Jarzynski equality in the presence of feedback control with multiple measurements. Our results are generalizations of the previous relevant works to the situations with general measurements and multi-heat baths. The obtained equalities involve additional terms that characterize the information obtained by measurements or the efficacy of feedback control. A generalized Szilard engine and a feedback-controlled ratchet are shown to satisfy the derived equalities.
