Abstract

By different coarse-graining procedures, we derive lower bounds on the total mean work dissipated in Brownian systems driven out of equilibrium. With several analytically solvable examples, we illustrate how, when, and where the information on the dissipation is captured.

摘要

通过不同的粗粒化程序，我们得出了非平衡驱动的布朗系统中耗散的总平均功的下限。通过几个可解析求解的例子，我们说明了如何、何时以及在何处获取关于耗散的信息。
