摘要翻译:
我们提出了一个微观哈密顿框架来开发类似麦克斯韦恶魔的引擎。我们的模型包括一个平衡热浴和一个非平衡热浴;后者是由外部平稳高斯噪声驱动产生的。我们开发的发动机,可以被认为是一种通过修改内部波动来提取功的装置。我们的理论分析集中在寻找在非平衡条件下产生涨落诱导输运所必需的基本成分。模型的一个重要结果是,当非线性熔池受到外界噪声的调制时,会发生净运动,即使两个熔池的温度相同,也会产生非零的有效温度。

英文摘要:
We present a microscopic Hamiltonian framework to develop Maxwell demon like engine. Our model consists of a equilibrium thermal bath and a non-equilibrium bath; latter generated by driving with an external stationary, Gaussian noise. The engine we develop, can be considered as a device to extract work by modifying internal fluctuations. Our theoretical analysis focusses on finding the essential ingredients necessary for generating fluctuation induced transport under non-equilibrium condition. An important outcome of our model is that the net motion occurs when the non-linear bath is modulated by the external noise, creating the non-zero effective temperature even when the temperature of both the baths are same.
