摘要:

信息就是力量这句俗语在随机热力学中有严格的形式,两者之间的定量等价有助于解释麦克斯韦恶魔减少熵的能力的悖论。在本文中,我们建立在早期的工作之间的相互作用的相对成本和利益的信息在产生工作的热力学发动机的循环操作(桑德伯格等人。2014年)。具体而言,我们研究了一般情况下的过阻尼粒子在时变电位(控制动作)的反馈,利用连续测量(非线性滤波)的热力学系综,产生适当的适应热力学第二定律,涉及信息。

英文摘要:

The common saying, that information is power, takes a rigorous form in stochastic thermodynamics, where a quantitative equivalence between the two helps explain the paradox of Maxwell's demon in its ability to reduce entropy. In the present paper, we build on earlier work on the interplay between the relative cost and benefits of information in producing work in cyclic operation of thermodynamic engines (by Sandberg etal. 2014). Specifically, we study the general case of overdamped particles in a time-varying potential (control action) in feedback that utilizes continuous measurements (nonlinear filtering) of a thermodynamic ensemble, to produce suitable adaptations of the second law of thermodynamics that involve information.
