论文摘要
非平衡热容量的概念对于更普遍的生物能源和活性材料的热量法很重要。它围绕着在不同的非平衡条件之间进行过度放松期间，过量的热量或多余的工作的概念。我们基于使用矩阵树和基质 - 孔定理的计算，为在图上的能量景观中移动的主动随机步行提供了确切的结果。该图形方法适用于在本地详细平衡的物理状态下的任何马尔可夫跳跃过程，并且不限于本文中给出的示例。
The notion of a nonequilibrium heat capacity is important for bio-energetics and for calorimetry of active materials more generally. It centers around the notion of excess heat or excess work dissipated during a quasistatic relaxation between different nonequilibrium conditions. We give exact results for active random walks moving in an energy landscape on a graph, based on calculations employing the matrix-tree and matrix-forest theorems. That graphical method applies to any Markov jump process under the physical condition of local detailed balance, and is not restricted to the examples given in this paper.
