非平衡量子过程的广义克劳修斯不等式

Generalized Clausius inequality for nonequilibrium quantum processes

Sebastian Deffner, Eric Lutz

摘要:

我们证明了受驱动量子系统的非平衡熵产生大于Bures长度,即系统的实际态与相应的平衡态之间的几何距离。这个普遍的下界将克劳修斯不等式推广到线性响应以外的任意非平衡过程。我们进一步推导了量子熵产生率的一个基本上界,并讨论了它与Bremermann-Bekenstein界的联系。

英文摘要:

We show that the nonequilibrium entropy production for a driven quantum system is larger than the Bures length, the geometric distance between its actual state and the corresponding equilibrium state. This universal lower bound generalizes the Clausius inequality to arbitrary nonequilibrium processes beyond linear response. We further derive a fundamental upper bound for the quantum entropy production rate and discuss its connection to the Bremermann-Bekenstein bound.
