论文摘要
在化学反应网络中，双重性只能出现远离平衡。它与控制参数是热力学力的一阶相变相关。在双态点，熵产生在热力学力方面是不连续的。我们表明，当系统可动时，熵产生的波动具有指数的体积依赖性。在相变时，指数的预成分是两个固定点之间有效势垒的高度。我们为Schlögl模型获得的结果可以扩展到任何化学网络。
In chemical reaction networks, bistability can only occur far from equilibrium. It is associated with a first-order phase transition where the control parameter is the thermodynamic force. At the bistable point, the entropy production is known to be discontinuous with respect to the thermodynamic force.We show that the fluctuations of the entropy production have an exponential volume-dependence when the system is bistable. At the phase transition, the exponential prefactor is the height of the effective potential barrier between the two fixed-points. Our results obtained for Schlögl's model can be extended to any chemical network.
