论文摘要
普遍接受的信条是，在典型情况下，熵产生的速率是非负的。我们表明，如果时间依赖性的外部扰动不会被响应函数的迅速衰减所补偿，那么这种断言并不是完全正确的。对于Drude模型的三种变体，这证明了这一点，以描述贵金属中的电导传导，即经典的游离电子气，Drude-Sommerfeld模型和扩展的Drude-Sommerfeld模型。该分析得出结论，讨论了潜在的实验验证和负熵生产率的后果。
It is a commonly accepted creed that in typical situations the rate of entropy production is non-negative. We show that this assertion is not entirely correct if a time-dependent, external perturbation is not compensated by a rapid enough decay of the response function. This is demonstrated for three variants of the Drude model to describe electrical conduction in noble metals, namely the classical free electron gas, the Drude-Sommerfeld model, and the Extended Drude-Sommerfeld model. The analysis is concluded with a discussion of potential experimental verifications and ramifications of negative entropy production rates.
