论文摘要
我们提出了一种简单的策略，用于从反馈控制的模型中构建麦克斯韦恶魔的信息棘轮或内存录像带模型。我们通过转换Annby-Andersson反馈控制的双量子点模型来说明我们的方法[Phys。 Rev. B 101，165404（2020）]到内存录像带模型。我们使用原始模型的基础网络结构来设计信息棘轮的一组位交互规则。新模型以较长的相互作用时间的限制进行分析求解。对于有限的时间相互作用，获得了操作模式的半分析相图。随机模拟用于验证理论结果。
We present a simple strategy for constructing an information ratchet or memory-tape model of Maxwell's demon, from a feedback-controlled model. We illustrate our approach by converting the Annby-Andersson feedback-controlled double quantum dot model [Phys. Rev. B 101, 165404 (2020)] to a memory-tape model. We use the underlying network structure of the original model to design a set of bit interaction rules for the information ratchet. The new model is solved analytically in the limit of long interaction times. For finite-time interactions, semi-analytical phase diagrams of operational modes are obtained. Stochastic simulations are used to verify theoretical results.
