我们表明,在小型开放系统中,与由扩展槽组成的环境耦合的熵产生主要是由环境从平衡状态的位移引起的,而不是像通常假设的那样,是系统和环境之间的相互信息引起的。后者的贡献受到Araki-Lieb不等式的强烈约束,因此与熵产生本身相比,它不是时间广泛性的。我们用系统环境动力学的精确数值计算证实了我们的结果。
We show that the entropy production in small open systems coupled to environments made of extended baths is predominantly caused by the displacement of the environment from equilibrium rather than, as often assumed, the mutual information between the system and the environment. The latter contribution is strongly bounded from above by the Araki-Lieb inequality and therefore is not time extensive, in contrast to the entropy production itself. We confirm our results with exact numerical calculations of the system-environment dynamics.
