标题： Extracting energy from non-equilibrium fluctuations without using information

摘要： 从涨落中提取能量一直是持续不断的努力。 一种重要的策略是使用基于信息的操作，这允许即使从热涨落中提取能量。 然而，尚不清楚一种对这些涨落无知的盲外部操作是否也会有效。 假设这种小规模操作，我们发现能量提取需要在某个频率区域具有负响应谱，这不可避免地需要内部电源来维持。 然后通过在这些频率下操作系统来提取能量。 负响应是任何适应缓慢外部操作的系统的固有特性，可以通过积分反馈控制实现。 这些通过一个可解模型得到验证。 显示英文摘要

摘要： Extracting energy from fluctuations has been an everlasting endeavor. An important strategy is to use information-based operation, which allows energy extraction even from thermal fluctuations. However, it remains unclear whether a blind external operation, ignorant of such fluctuations, will also work. Assuming such a small operation, we find that energy extraction requires a negative response spectrum in a certain frequency region, which inevitably requires an internal power source to maintain. Energy is then extracted by operating the system at these frequencies. Negative response is intrinsic to any system that adapts to a slow external operation, which could be realized through integral feedback control. These are demonstrated through a solvable model.
