We establish a generalization of the fluctuation theorem for partially masked nonequilibrium dynamics. We introduce a partial entropy production with a subset of all possible transitions, and show that the partial entropy production satisfies the integral fluctuation theorem. Our result reveals the fundamental properties of a broad class of autonomous as well as nonautonomous nanomachines. In particular, our result gives a unified fluctuation theorem for both autonomous and nonautonomous Maxwell's demons, where mutual information plays a crucial role. Furthermore, we derive a fluctuation-dissipation theorem that relates nonequilibrium stationary current to two kinds of equilibrium fluctuations.
我们建立了部分掩盖非平衡动力学涨落定理的推广。我们引入了包含所有可能跃迁子集的部分熵产生，并表明部分熵产生满足积分涨落定理。我们的结果揭示了一大类自主和非自主纳米机器的基本性质。特别地，我们的结果给出了自主和非自主麦克斯韦妖的统一涨落定理，其中互信息起着关键作用。此外，我们推导了一个涨落耗散定理，该定理将非平衡稳态电流与两种平衡涨落联系起来。
