连续Maxwell Demon中的功提取、信息量和Landauer界

Work extraction, information-content and the Landauer bound in the continuous Maxwell Demon

Marco Ribezzi-Crivellari, Felix Ritort

摘要:

在最近的一篇论文中,我们介绍了一个连续版本的麦克斯韦恶魔(CMD),是能够提取大量的工作,每个周期的系统状态的重复测量。在这里,我们强调它的主要特点,如在平均提取工作中所发挥的作用的Landauer限制,连续字符的测量过程和我们的连续麦克斯韦恶魔和自治麦克斯韦恶魔之间的差异。我们证明了朗道不等式的逆转依赖于工作提取物质的结晶和机械稳定性。我们还强调的鲁棒性的香农定义的信息内容的存储序列中的限制,其中工作提取是最大的,并推动了大的信息内容的罕见事件。

英文摘要:

In a recent paper we have introduced a continuous version of the Maxwell demon (CMD) that is capable of extracting large amounts of work per cycle by repeated measurements of the state of the system. Here we underline its main features such as the role played by the Landauer limit in the average extracted work, the continuous character of the measurement process and the differences between our continuous Maxwell demon and an autonomous Maxwell demon. We demonstrate the reversal of Landauer's inequality depending on the thermodynamical and mechanical stability of the work extracting substance. We also emphasise the robustness of the Shannon definition of the information-content of the stored sequences in the limit where work extraction is maximal and fuelled by the large information-content of rare events.
