Starting from Shannon’s definition of dynamic entropy, we propose a theory to describe the rare-event-determined dynamic states in condensed matter and their transitions and apply it to high-pressure ice VII. A dynamic intensive quantity named dynamic field, rather than the conventional thermodynamic intensive quantities such as temperature and pressure, is taken as the controlling variable. The dynamic entropy versus dynamic field curve demonstrates two dynamic states in the stability region of ice VII and dynamic ice VII. Their microscopic differences were assigned to the dynamic patterns of proton transfer. This study puts a similar dynamical theory used in earlier studies of glass models on a simpler and more fundamental basis, which could be applied to describe the dynamic states of more realistic condensed matter systems.

高压冰VII的动力性质

从香农对动力学熵的定义出发，我们提出了一种理论来描述凝结物质中稀有事件确定的动力学状态及其转变，并将其应用于高压冰VII。称为动态场的动态密集量，而不是诸如温度和压力之类的常规热力学密集量，被用作控制变量。动态熵对动态场曲线表明，在冰VII和冰VII的稳定区域中存在两个动态状态。他们的微观差异被分配给质子转移的动态模式。这项研究在更简单，更基础的基础上，将用于玻璃模型早期研究的相似动力学理论置于可以描述更为现实的凝聚态系统的动力学状态的基础上。
