Information ratchet with time-varying temperature
Physical Review E ( IF 2.4 ) Pub Date : 
Chern Lee, Hai Ye, Jianping Liu, and Li Zhang

We discuss a thermodynamic process with information and justify a general form of fluctuation relation. It shows that the fluctuation relation is valid whatever it is the temperature or Hamiltonian that drives the system out of equilibrium state. Based on the stochastic equation we obtain a non-equilibrium equality that involves both information and time-varying temperature. Through the processing of a harmonic system we demonstrate the validity of the equality by converting information into work. We also discuss the general second law of thermodynamics with time-varying temperature and verify its validity in an example by using information to reduce the total entropy.

随时间变化的信息棘轮

我们讨论具有信息的热力学过程,并证明波动关系的一般形式是合理的。它表明,无论是温度还是哈密顿量,使系统脱离平衡状态的波动关系都是有效的。基于随机方程,我们得到一个涉及信息和时变温度的非平衡等式。通过谐波系统的处理,我们通过将信息转换为工作来证明等式的有效性。我们还讨论了随时间变化的热力学的一般第二定律,并通过使用信息来减少总熵来验证其有效性。
