论文摘要
在文章中。 Rev. E 106，054617“收集信息以控制活性物质的非平衡状态”，作者研究了从一个非平衡稳态（NESS）到另一个NESS的过渡，通过改变驱动在光学陷阱中的棕色粒子的相关噪声。他们发现，过渡期间释放的热量与两个彩色噪声之间的光谱熵差成正比，这是一种让人联想到Landauer原理的方式。在这一评论中，我认为一般来说，释放的热量与光谱熵之间的发现关系并不成立，并且可以在显然失败的情况下提供示例。我还表明，即使在作者考虑的情况下，这种关系也不能严格地真实，并且仅在实验上进行了近似验证。
In the article Phys. Rev. E 106, 054617 "Harvesting information to control non-equilibrium states of active matter", the authors study the transition from one non-equilibrium steady-state (NESS) to another NESS by changing the correlated noise that is driving a Brownian particle held in an optical trap. They find that the amount of heat that is released during the transition is directly proportional to the difference of spectral entropy between the two colored noises, in a fashion that is reminiscent of Landauer's principle. In this comment I argue that the found relation between the released heat and the spectral entropy does not hold in general, and that one can provide examples of noises where it clearly fails. I also show that, even in the case considered by the authors, the relation cannot be rigorously true and is only approximately verified experimentally.
